How are mass and weight different?
(A) Weight is the amount of matter and mass is the effect of gravity on weight.
(B) Weight is the space an object takes up and mass is the effect of gravity on mass.
(C) Mass is the space an object takes up and weight is the effect of gravity on mass.
(D) Mass is the amount of matter and weight is the effect of gravity on mass.
Answer:
D
Explanation:
D, Mass is the amount of matter in an object, it is measured in kg and does not change with gravity. Weight is the effect of gravity on mass, it is measured in Newtons (as it is a force) and changes with gravity. E.g. If you went to the moon your weight would change due to the change in gravity but your mass would stay the same.

How would a chart of mid-17th century religious beliefs differ from this chart?
Fewer people would believe in a single God because most people believed in multiple gods.
Fewer people would identify as atheist because people who did not identify with the official religion did not say so out loud.
More people would list their religion as unknown because there were no strong religious entities during this era.
More people would believe in a spirit or life force because such beliefs were encouraged during this era.
Answer:
The correct answer is B) Fewer people would identify as an atheist because people were not willing to share alternative religious beliefs publically.
Explanation:
A chart of mid-17th-century religious beliefs differs from this chart in that Fewer people would identify as an atheist because people were not willing to share alternative religious beliefs publically.
In the 1600s, people did not have total freedom of speech if they had any. The church had a tremendous influence in the life of people and religious beliefs defined societies and families. The Church exerted its power and influence in many aspects of the people's lives and something out of the purview of the church or different to the religious beliefs of the Church was considered to be sacrilegious. The Church prosecuted people for being against the Church, so people of that time preferred to say that they were religious people supporting the church. Being an atheist was not really an option in the 17th century.

Answer: The first one
Fewer people would identify as atheist because people who did not identify with the official religion did not say so out loud.
Explanation:
A boat heads directly eastward across a pier at 12 meters per second. If the current in the river is flowing
at 5.0 meters per second due south, what is the magnitude of the boat's resultant velocity
Answer: 13 m/s
Explanation: The two vectors form a 5-12-13 right triangle. the magnitude of their resultant is the hypotenuse, which is 13 m/s.
The magnitude of the boat's resultant velocity (V) is 13 meters per second.
The velocity (v₁) of the boat heading in the eastward direction is in +ve (x-direction).
The velocity (v₂) of the current flowing in the south direction is in -ve (y-direction).
The magnitude of the boat's resultant velocity (V) can be determined by using the Pythagoras' rule:
∴
V² = V₁² + V₂²
V² = (12 m/s)² + (-5.0 m/s)²
[tex]\mathbf{V = \sqrt{(12 m/s)^2 + (-5.0 m/s)^2}}[/tex]
[tex]\mathbf{V = \sqrt{(144 m/s) + (25m/s)}}[/tex]
[tex]\mathbf{V = \sqrt{(169 \ m/s) )}}[/tex]
V = 13 m/s
Therefore, we can conclude that the magnitude of the boat's resultant velocity (V) is 13 meters per second.

) When coal is burned completely into carbon dioxide and other gases, the total
amount of matter of the gases _____.
Answer:
This question is incomplete
Explanation:
This question is incomplete. The process described in the question is combustion; where a substance burns completely in excess oxygen to produce mainly carbon dioxide and then other gases. There is no chemical equation for this particular combustion reaction because coal is a mixture.
However, the amount of the matter of the gases produced from this combustion must be equal to the total number/amount of matter that constitutes the coal because of the law of conservation of matter that states matter can neither be created nor destroyed.
A car accelerates uniformly in a straight line from rest at the rate of 3.7 m/s2
What is the speed of the car after it has traveled 63 m? Answer in units of m/s.
How long does it take the car to travel 63 m? Answer in units of s
Explanation:
Using equations of motion :
(A) we know that,
u = 0
a = 3.7 m/s^2
S = 63
[tex] {v}^{2} = {u}^{2} + 2as[/tex]
[tex]v = \sqrt{0 + 2 \times 3.7 \times 63} = 21.6 \: m{s}^{ - 1} [/tex]
(B)
v = u + at
21.6 = 0 + 3.7 * t
t (time to reach 63 m) = 5.83 seconds
A long wire of diameter D= 1 mm is submerged in an oil bath of temperature [infinity] T[infinity]= 15°C. The wire has an electrical resistance per unit length of Re′= 0.01 Ω/m. If a current of I= 96 A flows through the wire and the convection coefficient is h= 500 W/m2·K, what is the steady-state temperature of the wire? From the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°C of the steady-state value? The properties of the wire are rho= 8000 kg/m3, c= 500 J/kg·K, and k= 20 W/m·K.
Answer:
a) what is the steady-state temperature of the wire?
83.67°C
b) From the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°C of the steady-state value?
8.31s
Explanation:
a) what is the steady-state temperature of the wire?
From the above question we are given the following values:
Oil bath temperature = 15°C.
Diameter of wire = 1mm
Converting to m(meter)
1 mm = 0.001m
The wire has an electrical resistance per unit length of Re′= 0.01 Ω/m. Current of I= 96 A
Convection coefficient is h= 500 W/m²·K,
Temperature in steady state formula =
Temperature + I² × Re' /π × D × h
= 25°C + 96² × 0.01/π × 0.001 × 500
= 25°C + 92.16/1.5707963268
= 25°C + 58.670878232
= 83.670878232°C
≈ 83.67°C
b)From the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°C of the steady-state value?
For question b, we are given the following values
rho= 8000 kg/m3, c= 500 J/kg·K, and k= 20 W/m·K
Formula
= Exp( -4 × h/rho × c × k)
=Exp(- 4 × 500 W/m²·K)/8000 kg/m³ ×
500 J/kg·K × 20 W/m·K
= 8.31s

What is the mass of the object being measured?
A triple beam balance is shown. The first slider is at the 70 gram mark. The second slider is at the 300 gram mark. The third slider is at the 5 gram mark.
Answer:
m = 375 [gram]
Explanation:
A triple Beam balance is an instrument very easy to use, since we only have to perform the arithmetic sum of each of the weights that are recorded in each beam
m = 300 + 70 + 5 = 375 [gram]
For a better understanding, the following image is attached, with values on each beam, which should be read.
The largest mass is in the indicator of 100 [gram], the second mass is in the indicator of 20 [gram] and the third is in the indicator of 5.8 [gram]. Thus the arithmetic sum corresponds to:
M= 100 + 20 + 5.8 = 125.8 [gram]
Note: it is important that when the instrument is in balance, the opposite end of the beam should indicate a position of zeros.

A golf ball is projected at an angle of 30 degrees to the ground. If velocity of the object is 20 m/s, calculate the horizontal component of this velocity
Answer: 17.3
Explanation:
The horizontal component of the velocity of the projectile is equal to 17.32 m/s.
What is projectile motion?
A projectile is an object that is in flight after being projected. The acceleration acting is in the vertical direction which is due to gravity (g) in a projectile motion. Therefore, equations of motion can be applied separately on X-axis and Y-axis to find the parameters.
If any object is projected with the velocity v, making an angle θ (theta) from horizontal. Then the horizontal component of the initial velocity will be equal to v cosθ.
The vertical component of initial velocity is v sinθ. The horizontal component of velocity remains the same as no acceleration is acting horizontally during the entire motion of a projectile.
Given, the angle of the projectile with the ground, θ = 30°
The initial velocity of the projectile, v = 20 m/s
The horizontal component of this velocity, = v cosθ = 20 × cos30°
= 20 × 0.866
= 17.32 m/s
Therefore, the horizontal component of this velocity is 17.32 m/s.

How is retrograde motion different from normal diurnal motion
Answer:
Diurnal motion, apparent daily motion of the heavens from east to west in which celestial objects seem to rise and set, a phenomenon that results from the Earth's rotation from west to east. The axis of this apparent motion coincides with the Earth's axis of rotation. Retrograde motion is an APPARENT change in the movement of the planet through the sky. It is not REAL in that the planet does not physically start moving backwards in its orbit. It just appears to do so because of the relative positions of the planet and Earth and how they are moving around the Sun.
A soccer ball rolls across a field with
an initial velocity of 14.9. Due to friction, it slows down at a rate of .5 until eventually coming to a stop. How far did it roll AND how long did it take to get there?
Answer:
The value is [tex]s = 222.01 \ m[/tex]
Explanation:
From the question we are told that
The initial velocity is [tex]u = 14.9 \ m/s[/tex]
The deceleration is [tex]a = - 0.5[/tex]
Generally from kinematic equations we have that
[tex]v^2 = u^2 + 2as[/tex]
Here v is 0 m/s because the velocity of the ball when at rest is zero so
[tex]0^2 = 14.9^2 + 2 (-0.5)s[/tex]
=> [tex]s = \frac{222.01}{1}[/tex]
=> [tex]s = 222.01 \ m[/tex]
