F - False.
Its greatest kinetic energy is at the point of release.
It has the least kinetic energy, zero, at its highest point in its path.
Answer:
People can hear sounds at frequencies from about 20 Hz to 20,000 Hz,
The answers are 3.3kWh, 1.2kWh, and 120kWh.
Multiply the amount of kW used per hour by the amount of time it was powered and you receive your answer.
F = ma
Rearrange this so acceleration is the subject:
A = f/m
Now input your values into this equation for the first question :
A = f/m
A = 15/45
A = 0.33333333 m/s
Then using this same equation change the force of 15 to 25 :
A = f/m
A = 25/45
A = 0.55555556 m/s
For the last question keep the force of 15N but change the mass to 70kg into the same equation :
A = f/m
A = 15/70
A = 0.21 m/s (rounded)
Answer:
What I like the most about engaging to different recreational activities is that these contribute to my entertainment and relax after working.
That is, recreational activities allow individuals to abstract from their daily responsibilities, encouraging distraction and concentration of the individual on issues of less importance, allowing them to relax.
Therefore, in my case I love that different recreational activities, such as sports or social gatherings, allow me to abstract from my responsibilities and allow me to enjoy moments of fun.
