Answer:

The Basal Metabolic Rate of 88 kilocalories per hour is equal to 102.276 watts.

Explanation:

A watt is equal to 1 joule per second, a kilocalory equals 4184 joules and a hour equals 3600 seconds. We convert the Basal Metabolic Rate (BMR) from kilocalories per hour into watts by following conversion:

[tex]x = 88\,\frac{kcal}{hr}\times \frac{4184\,J}{1\,kcal}\times \frac{1\,h}{3600\,s}[/tex]

[tex]x = 102.276\,W[/tex]

The Basal Metabolic Rate of 88 kilocalories per hour is equal to 102.276 watts.

Answer:

110.7Joules

Explanation:

Work is said to be done when the force applied to a body cause the body to move through a distance. Mathematically:

Work done = Force * Distance

Given the following

Force = 270 -0  = 270N

Distance moved = 0.410m

Required

The work done

Substitute the given parameters into the formula

Workdone = 270 * 0.41

Workdone = 110.7Joules

Hence the work done in pulling the bow is 110.7Joules

Answer:

B: At the launch point

Explanation:

We are told that after the explosion, one of the halves landed at the point Y, which is a distance 2R to the right of the launch point. Now, if air resistance is negligible, it means the other half will land at the launch point. This is clear from the model projectile motion curve of this explosion I've done in wolfram and attached.

Answer:

Therefore, the correct option is c: 0.

Explanation:

We can find the speed of the combined object by conservation of linear momentum:

[tex] p_{i} = p_{f} [/tex]

[tex] m_{1}v_{1_{i}} + m_{2}v_{2_{i}} = m_{1}v_{1_{f}} + m_{2}v_{2_{f}} [/tex]

Where:

"i" is for initial and "f" is for final

m₁: is the mass of the first object = m

m₂: is the mass of the second object = 3m

v₁: is the velocity of the first object

v₂: is the velocity of the second object

[tex] mv - 3m\frac{v}{3} = (m + 3m)v_{f} [/tex]

[tex] mv - mv = 4mv_{f} [/tex]

[tex] v_{f} = 0 [/tex]

Therefore, the correct option is c: 0.

Explanation:

The two most common isotopes of tin have atomic masses of 118 and 120 and have the key difference that the heavier isotope has 2 more neutrons than the lighter one.

Tin is the element that has the largest number of stable isotopes, only out of the ten are potentially radioactive but have not been observed to decay.

We know that Tin 118 and Tin 120 are the isotopes of the tin, but the key difference between them is that the Tin 120 has two more neutrons than Tin118, therefore, the isotopic mass of the two is different as well.

Mass of Tin118 < Mass of Tin120

Therefore, from all the provided options the correct option is that the heavier isotope has two more neutrons than the lighter isotope.

Hence, the correct option is d.

Answer:

The material that Emily invented can be easily repaired by shining ultraviolet light on it.

Explanation:

Answer:

Explanation:

The charged particle will experience a force towards one of the plates , in direction perpendicular to its initial velocity because electric field is between the plates .

The force experienced by it = q E

acceleration a  = qE / m , where m is mass of the charged particle .

The particle will have two velocity at the time it leaves the space between plates .

Horizontal velocity = initial horizontal velocity = v .

vertical velocity is created by force qE

Time taken by horizontal velocity to cover distance L

t = L / v

vertical velocity attained V = u + at

0 + at  ( time taken by vertical velocity and time taken by horizontal velocity are equal )

vertical velocity = (qE/ m) x (L/v) = qEL / mv

Resultant velocity = [tex]\sqrt{(\frac{v}{1} )^2+(\frac{qEL}{mv})^2 }[/tex]

= [tex]\sqrt{(v^2+(\frac{qEL}{mv})^2 }[/tex]

This gives the magnitude of resultant velocity .

Answer:

1428.6m/s²

Explanation:

Given parameters:

Force applied on the body  = 40N

Mass of the body  = 28g

                    1000g  = 1kg

                      28g will therefore be 0.028kg

Unknown:

Acceleration  = ?

Solution:

To solve this problem, we use the expression derived from Newton's second law of motion.

         Force  = mass x acceleration

Insert the parameters and solve;

            40  = 0.028 x acceleration

           Acceleration  = [tex]\frac{40}{0.028}[/tex]   = 1428.6m/s²

Explanation: did the test

Answer:

Explanation:

Answer:

the correct answer is B      r =√2   R

Explanation:

To solve this exercise we will use the force of gravity, at two points when the rocket is on the platform and when it is at the desired height.

Rocket with cargo on the platform

              [tex]F_{g} = G \frac{ m M }{R^2} = W[/tex]

where m is the mass of the rocket and the charge, M the mass of the earth and R the distance from the center of the earth

Rocket loaded at desired height

              [tex]F_{g} = G \frac{m M}{r^2 } = \frac{W}{2}[/tex]

we write our two equations

        W = g m M / R²

        [tex]\frac{W}{2}[/tex] = G m M / r²

we match to solve them

         Gm M / R² = 2 Gm M / r²

         1 / R² = 2 / r²

          r =√2   R

therefore the correct answer is B

Answer:

    [tex]v_b[/tex] = 17.98 m / s

Explanation:

To solve this exercise we will use the kinematics relations in one dimension, let's start by looking for the acceleration between points A and C

         v = v₀ + a t

         a = [tex]\frac{v - v_o}{t}[/tex]

         a = [tex]\frac{19 - 14}{3.50}[/tex]

         a = 1.43 m / s²

this acceleration is uniform throughout the path.

Let's find the velocity at point B

          [tex]v_c = v_b + a t[/tex]

          [tex]v_b = v_c - a t[/tex]

let's calculate

          [tex]v_b[/tex] = 19 - 1.43 1.40

          [tex]v_b[/tex] = 17.98 m / s

Answer:

the length of an antenna one-half wavelength long for sending radio at 300 Hz is 500 km

Explanation:

Given the data in the question;

we know that wave length is;

λ = c/f

c is the speed of voice ( 3 × 10⁸  m/s )

frequency f = 300 Hz

so we substitute

λ = 3 × 10⁸ / 300

λ = 1000000 m

we know that; 1 km = 1000 m

so

λ = 1000000 m / 1000

λ = 1000 km

hence, an antenna one-half wavelength will be;

λ /2

=  1000 km / 2

= 500 km

Therefore, the length of an antenna one-half wavelength long for sending radio at 300 Hz is 500 km

Answer:

a) The velocity of the rock during ascent at 180 meters above the surface is approximately 17.799 meters per second.

b) The height of the rock from the ground is 219 meters from the ground.

Explanation:

a) The rock experiments a free fall, in which this element is projected upwards, decelerated until rest is reached and then it falls down. Please notice that free fall is a case of uniformly accelerated motion, in which object is accelerated by gravity. The velocity of the rock is described by the following kinematic equation:

[tex]v = \sqrt{v_{o}^{2}+2\cdot a\cdot \Delta s}[/tex] (1)

Where:

[tex]v_{o}[/tex] - Initial velocity, measured in meters per second.

[tex]v[/tex] - Final velocity, measured in meters per second.

[tex]a[/tex] - Gravitational acceleration, measured in meters per square second.

[tex]\Delta s[/tex] - Travelled distance, measured in meters.

If we know that [tex]v_{o} = 30\,\frac{m}{s}[/tex], [tex]a = -1.62\,\frac{m}{s^{2}}[/tex] and [tex]\Delta s = 180\,m[/tex], then the velocity during ascent at 180 meters is:

[tex]v =\sqrt{\left(30\,\frac{m}{s} \right)^{2}+2\cdot \left(-1.62\,\frac{m}{s^{2}}\right)\cdot (180\,m) }[/tex]

[tex]v \approx 17.799\,\frac{m}{s}[/tex]

The velocity of the rock during ascent at 180 meters above the surface is approximately 17.799 meters per second.

b) The height of the rock is calculated from this kinematic formula:

[tex]s = s_{o}+v_{o}\cdot t +\frac{1}{2}\cdot a \cdot t^{2}[/tex] (2)

Where:

[tex]s_{o}[/tex] - Initial position of the rock, measured in meters.

[tex]s[/tex] - Final position of the rock, measured in meters.

[tex]v_{o}[/tex] - Initial velocity of the rock, measured in meters per second.

[tex]t[/tex] - Time, measured in seconds.

[tex]a[/tex] - Acceleration, measured in meters per square second.

If we know that [tex]s_{o} = 0\,m[/tex], [tex]v_{o} = 30\,\frac{m}{s}[/tex], [tex]t = 10\,s[/tex] and [tex]a = -1.62\,\frac{m}{s^{2}}[/tex], then the height of the rock from the ground is:

[tex]s = 0\,m + \left(30\,\frac{m}{s} \right)\cdot (10\,s)+\frac{1}{2}\cdot \left(-1.62\,\frac{m}{s^{2}} \right)\cdot (10\,s)^{2}[/tex]

[tex]s = 219\,m[/tex]

The height of the rock from the ground is 219 meters from the ground.

Answer:

F = 1.185 x 10⁻¹⁰ N

Explanation:

The force of gravitation between two objects is given by Newton's Law of Gravitation. According to this law:

[tex]F = \frac{Gm_{1}m_{2}}{r^{2}}\\[/tex]

where,

F = Gravitational Force between satellites = ?

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²

m₁ = m₂ = mass of each satellite = 2000 kg

r = distance between both satellites = 1500 m

Therefore,

[tex]F = \frac{(6.67\ x\ 10^{-11}\ Nm^{2}/kg^{2})(2000\ kg)(2000\ kg)}{(1500\ m)^{2}}\\\\[/tex]

F = 1.185 x 10⁻¹⁰ N
