Answer:
Direction and Size both are required .
Answer:
117.6 m/s downward
Explanation:
The penny is moving with uniform accelerated motion (free fall motion), so we can find its vertical velocity at time t with the following suvat equation:
v = u + at
where
v is the velocity at time t
u is the initial velocity
a is the acceleration
The penny starts at rest, so
u = 0
Also, the acceleration is the acceleration of gravity,
where we have chosen upward as positive direction, so the acceleration is negative, since it is downward.
Substituting t = 12 s, we find the velocity of the penny when it hits the ground:
downward, since the sign is negative.
Answer:
It gives you the symbol, mass, and the number of protons, neutrons, and electrons of elements.
The capacity of muscles to maintain a force, over a period of time or uses a single maximum force over any range of motion is called Muscular Endurance. It can sustain repetitive contractions against a resistance for an extended period of time. It is one of the constituents of muscular fitness.
I believe that is true, yes!
