Explanation:
1600÷8=200s 1200÷90=13.33s 50÷15= 3.33s (1600+1200+50)/(200+13.33+3.33) = 13.15m/s
Why space time curves in the presence of mass or energy?
Answer: A massive body such as the Earth causes gravity because matter is concentrated energy, hence E=mc². But note that a no mass photon also causes gravity, as done any kind of energy, not just mass-energy. Moreover the energy doesn't actually bend the surrounding space.

Given:
= 323 K
= 293 K
specific heat of aluminium,
specific heat of water,
Formula Used:
Q = m
Solution:
Let the temperature at equilibrium be ' ' K
Now at equilibrium, using the given formula:
Temperature at equilibrium, = 295.513 K
Now, change in entropy(in J/K) is given by:
Q = m
= 12094.28 cal
Now,
= 40.93 cal/K = 9.78 J/K
Therefore change in entropy is given by:
Answer:
Assuming rightward is positive, the velocity is positive whenever the car is moving to the right, and the velocity is negative whenever the car is moving to the left. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.
