In order for work to be done, what must be true?
Amiraneli [1.4K]

Answer:

option c

Explanation:

Work is said to be done when a force moves a body over a distance, in the direction of force applied.

Work done = force x distance (in the direction of the force)

Therefore work = force x displacement

As displacement is distance in a specific or specified direction.

The potential energy of an apple is 6.00 joules. The apple is 3.00-meters high. What is the mass of the apple?
BaLLatris [955]

                                         Potential energy  =  (mass) x (gravity) x (height)

Divide each side by (G x H) :      Mass  =  PE / (G x H) 

PE = 6 joules
Gravity = 9.8 m/s
Height = 3 m
                                                     Mass  =  6 / (9.8 x 3) =

                                                                     6 / (29.4)  =  <em>0.204 kg</em>
 
                                  (weighs about 2 newtons or 7.2 ounces on Earth)

4. A spring is stretched 0.5 m from equilibrium. The force constant (k) of the
makkiz [27]

Answer:

31.25

Explanation:

The formula for the potential energy of a spring is \frac{1}{2}kx^2, where x is the distance in meters the spring is stretched. Plugging in the numbers that you are given, you get \frac{1}{2}\cdot 250\cdot 0.25=31.25. Hope this helps!

-g With what tension must a rope with length 2.50 m and mass 0.120 kg be stretched for transverse waves of frequency 40.0 Hz to
Alex17521 [72]

Answer:

43.2 N

Explanation:

\lambda = Wavelength = 0.75 m

f = Frequency = 40 Hz

m = Mass of string = 0.12 kg

L = Length of string = 2.5 m

\mu = Linear density = \dfrac{m}{L}

Velocity of wave is given by

v=\lambda f\\\Rightarrow v=0.75\times 40\\\Rightarrow v=30\ m/s

The tension in string is given by

T=v^2\mu\\\Rightarrow T=30^2\times \dfrac{0.12}{2.5}\\\Rightarrow T=43.2\ N

The tension in the string is 43.2 N

How far from the surface of Earth is the magnitude of Earth's gravitational field equal to 7.86 N/kg?
AfilCa [17]

Answer:

7.48 x 10⁵ m

Explanation:

g = 7.86 N/kg

M = 5.97 x 10²⁴ kg, R = 6.37 x 10⁶ m.

Find height h

g = GM/(R + h)²

(R + h)² = GM/g = 6.67 x 10⁺¹¹ x 5.97 x 10²⁴ /7.86 = 5.066 x 10¹³

R + h = 7.12 x 10⁶ m

so

h =  7.12 x 10⁶ - 6.37 x 10⁶ = 7.48 x 10⁵ m
