the first one
explanation:
hi:3
I dont have a calculator but the equation for average acceleration is a=(change in velocity)/time. Subtract the intial velocity by the final and divide that by time
Answer:
Option (A).
Explanation:
When a hot and a cold objects come in thermal contact with each other,exchange of heat takes place between them until thermal equilibrium is reached.
In this process thermal energy flows from high temperature to low.
Therefore, when a beaker of boiling water comes in touch with a block of ice,
Thermal energy starts flowing from boiling water to block of ice until equilibrium is established.
Option (A) will be the answer.
If you're moving at 70 mi/hr, then you cover 33.88 feet in 0.33 sec. If you're moving at 1,000 ft/sec, then you cover 33 feet in 0.33 sec. 70 mph and 1,000 fps are not equivalent. 1,000 fps is about 682 mph, whereas 70 mph is about 103 fps.
