Answer:
a) from the hotter object to the cooler object
Explanation:
temperature moves by conduction, which is associated with the movement of atoms or molecules and the always move from hight temperatures to lower temperatures to attain thermal equilinrium of the system.
so when two objects are placed together and have different temperatures then the system is not in thermal equilibrium and to attain it, temperature can only move to coller object and not from the coller object according to thermodynamics.
I’m going to assume initial velocity is 0.
Use Newton’s second law:
F = m•a
F/m = a
14.0/32.5kg= 28/65 m/s^2
Use constant SUVAT acceleration formulae:
S- displacement - what we need to find out
U - initial velocity - 0
V
A - 28/65 m/s^2
T - 10 seconds
S = ut + 1/2at^2
Since u = 0
S = 1/2at^2
1/2• 28/65 • 10^2 = 21.5metres~
Answer is 21.5 metres
~Hoodini, here to help.
For any eclipse, all three bodies are in the same straight line. For a solar eclipse, the moon is the one in the middle. For a lunar eclipse, the Earth is the one in the middle.
Answer:
20 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
r = Radius of robot = 0.5 m
= Angular acceleration = 2 rad/s²
Linear acceleration is given by
While speeding up time taken is 10 seconds
The time taken to slow down is 10 seconds
Total time the trial is rum is 10+10 = 20 seconds
