Billy is pulling his sister Joslyn in the sled. Based on your knowledge of F=ma, describe what would
happen to the motion of the sled if Joslyn's friend Lisa also wanted to ride.
Answer:
the motion of the sled decrease
Explanation:
the mass increase
The acceleration of the sled will is inversely proportional to the mass on it. Therefore, the motion of the sled would slow if Joslyn's friend Lisa also wanted to ride.
What is acceleration?Acceleration in mechanics can be described as the rate of change of velocity of an object with respect to time. The acceleration of an object is a vector quantities with magnitude and direction.
The S.I. unit for acceleration can be represented as m/s² the net balance of all external forces acting is equal to the magnitude of the net resulting force.
The force (F) acting on an object is equal to the product of the mass (m) of the object and acceleration (a) of an object.
F = ma
And, a = F/m
As shown in the above equation, the mass of the object is inversely proportional to the acceleration of the object, therefore, the acceleration of the sled decrease as the mass on it increases.

You apply a 325 N force to a heavy crate with a rope that makes a 29.0° angle with the horizontal, if you pull the crate a distance of 5.37 m, how much work was done by you?
Answer:
W = 1526.43 J
Explanation:
Given that,
Force acting on a heavy crate, F = 325 N
The rope will make 29.0° angle with the horizontal
The distance covered by the crate, d = 5.37 m
We need to find the work done by the crate. The work done by an object is given by :
[tex]W=Fd\cos\theta\\\\=325 \times 5.37\times \cos29\\\\=1526.43\ J[/tex]
So, the required work done is 1526.43 J.
Levi decides to examine the effect of fertilizer on the growth of tomato plants. He chooses four plants for his experiment and applies varying amounts of fertilizer to three of them. He does not apply fertilizer to one plant.
Over a 15-day period, the plants receive fertilizer on Days 1, 4, 7, 10, and 13. Levi measures the height of all of his plants with a meter stick on days 3, 6, 9, 12, and 15. He also makes sure to hold all experimental factors constant except for the fertilizer.
Where should the independent and dependent variables of Levi's experiment be placed when graphed?
Select all that apply.
the amount of fertilizer; y-axis
plant height; y-axis
the amount of fertilizer; x-axis
plant height; x-axis
Explanation:
Over a 15-day period, the plants receive fertilizer on Days 1, 4, 7, 10, and 13.
Levi measures the height of all of his plants with a meter stick on days 3, 6, 9, 12, and 15.
Independent variable is the amount of fertilizers given to the plants. The height of the plant depends on the amount of the fertilizers. It is the dependent variable.
On x-axis : The amount of fertilizer
On y -axis : Plant height

by how many times will the kinetic energy of a body increaseif its speed is tripled? show by calculation.
Answer:
9 times
Explanation:
Mass of a body remains constant.
Let the mass of a body be 'm'
Let the speed of the body be 'v'
Initial Kinetic Energy (K.E.) = [tex] \frac{1}{2} m {v}^{2} [/tex]
When speed is tripled , new speed = 3v
Mass of body = m (Mass is always constant)
Final Kinetic Energy (K.E.") =
[tex] \frac{1}{2} \times m \times {(3v)}^{2} [/tex]
[tex] = > \frac{1}{2} \times m \times 9v[/tex]
[tex] = > 9( \frac{1}{2} m {v}^{2} )[/tex]
But we already know that [tex]k.e. = \frac{1}{2} m {v}^{2} [/tex]
Hence
[tex] = > final \: k.e. = 9(initial \: k.e.)[/tex]

A Nerf gun is shot straight up from the ground with an initial velocity of 14.0 m/s. What is the total time the projectile is in the air?
PLEASE SHOW WORK WILL MARK BRAINLIEST
The projectile has a height h at time t given by
h = (14.0 m/s) t - 1/2 g t ²
where g = 9.80 m/s² is the magnitude of the acceleration due to gravity. Solve for t when h = 0 :
0 = (14.0 m/s) t - 1/2 g t ²
0 = 1/2 t (28.0 m/s - g t )
1/2 t = 0 or 28.0 m/s - g t = 0
The first equation says t = 0, which refers to the moment the gun is first fired, so we ignore that solution. We're left with
28.0 m/s - g t = 0
t = (28.0 m/s) / g
t = (28.0 m/s) / (9.80 m/s²)
t ≈ 2.86 s
When illuminated with monochromatic light, a double slit produces a pattern that is a combination of single-slit diffraction and double-slit interference. This can be easily seen if the separation between the slits and the size of slits are related by simple fractions. Find the ratio of the width of the slits to the separation between them, if the first minimum of the single slit pattern falls on the fifth maximum of the double slit pattern.
Answer:
The ratio is [tex]k:d = 1 : 5[/tex]
Explanation:
From the question we are told that
The first minimum of the single slit pattern falls on the fifth maximum of the double slit pattern.
Generally the condition for constructive interference for as single slit is
[tex]ksin(\theta) = n\lambda[/tex]
Here k is the width of the slit and n is the order of the fringe and for single slit n = 1 (cause we are considering the first maxima)
Generally the condition for constructive interference for as double slit is
[tex]dsin\theta = m\lambda[/tex]
Here d is the separation between the slit and m is the order of the fringe and for double slit m = 5 (cause we are considering the first maxima)
=> [tex]dsin\theta = 5\lambda[/tex]
So
[tex]\frac{ksin(\theta)}{dsin(\theta)} = \frac{\lambda}{5\lambda}[/tex]
=> [tex]\frac{k }{d} = \frac{1}{5}[/tex]
So
[tex]k:d = 1 : 5[/tex]

The majority of electric motors work by creating force in the form of torque imparted to the motor shaft through the interplay of the magnetic field of the motor and electric current in a wire winding.
Electric generators function with a reversed power flow, transforming mechanical energy into electrical energy, and are mechanically identical to electric motors.
Electric motors can be powered by alternating current (AC) sources like a power grid, inverters, or electrical generators or by direct current (DC) sources like batteries or rectifiers.

Answer:
graph 1
Explanation:
When it comes to a graph showing "constant acceleration," the line should be straight and upward (positive acceleration) or straight and downward (negative acceleration). The variables for acceleration are time and velocity. The independent variable (time) should be placed on the x-axis while the dependent variable (velocity) should be placed on the y-axis. As time increases, the velocity increases the same way. It doesn't slow down or changes. This makes it constant. They are also directly proportional to each other. This is evident on the first graph.

A. What is the decay constant for Polonium-212 if the half-life is 299x10-9 s?
Answer:
2.318·10^6
Explanation:
You want to find k such that ...
e^-k = (1/2)^(1/(299·10^-9))
-k = ln(1/2)/(299·10^-9)
k = ln(2)/(299·10^-9) ≈ 2.318·10^6
An airplane's speed increased from 100m/s to 160m/s, at the average rate of 15m/s^2. How long did it take for the plane to complete this increase in speed?
Answer:
4s
Explanation:
Using the formula of motion as follows:
V = u + at
Where;
V = final velocity (m/s)
U = initial velocity (m/s)
a = acceleration (m/s)
t = time (s)
Based on the provided information, v = 160m/s, u = 100m/s, a = 15m/s², t = ?
V = u + at
160 = 100 + 15t
160 - 100 = 15t
60 = 15t
t = 60/15
t = 4seconds.
Therefore, the time it takes for the plane to complete this increase in speed is 4s.
The speed of sound in human tissue is about 1600 m/s. If an ultrasound pulse takes
1.5 x 10--s to travel through a tissue, what is the thickness of the tissue in mm?
Answer:
The thickness of the tissue is : 2.4 x 10⁷ mm
Explanation:
The general formula for speed is the distance travelled divided by the time taken.
In this case,
Speed = 1600 m/s ------speed of sound in human tissue
Time = 1.5 * 10 seconds -----time of taken for the ultrasound pulse to go through a certain thickness of a tissues
The thickness of the tissue here is the distance as per the speed formula, hence;
Tissue thickness = Speed of sound * time taken by ultrasound pulse
Tissue thickness= 1600 * 1.5*10 =24000 m
1 m= 1000 mm
24000m = 24000*1000 mm
= 2.4 x 10⁷ mm
An airplane is traveling at an altitude of 15,490 meters. A box of supplies is dropped from its cargo hold. What is the cargo's velocity when it hits the ground? (Show your work and do not forget units)
Answer :
556.59 m/s.
Explanation:
Given that,
An airplane is traveling at an altitude of 15,490 meters.
A box of supplies is dropped from its cargo hold. We need to find the velocity of cargo when it hits the ground.
The initial velocity of the box is 0 as it as at rest. Let v is the velocity of cargo when it hits the ground. We can find it using third equation of motion as follows :
[tex]v^2-u^2=2as[/tex]
Put u = 0 and a = g
[tex]v^2=2gs\\\\v=\sqrt{2gs} \\\\v=\sqrt{2\times 10\times 15490 } \\\\v=556.59\ m/s[/tex]
So, when it hits the ground its velocity is 556.59 m/s.
Chris threw a basketball a distance of 27.5 m to score and win his
high school basketball game. If the shot was made at a 50.0° angle
above the horizontal, what was the initial speed of the ball?
Answer:
v₀ = 16.55 m/s
Explanation:
This motion of the ball can be modeled as a projectile motion with following data:
R = Range of Projectile = 27.5 m
θ = Launch Angle = 50°
g = acceleration due to gravity = 9.81 m/s²
v₀ = Initial Speed of Ball = ?
Therefore, using formula for range of projectile, we have:
[tex]R = \frac{v_{0}^2\ Sin2\theta}{g}\\\\v_{0}^2 = \frac{Rg}{Sin2\theta}\\\\v_{0}^2 = \frac{(27.5\ m)(9.81\ m/s^2)}{Sin100^o}\\\\v_{0} = \sqrt{273.93\ m^2/s^2}[/tex]
v₀ = 16.55 m/s
