Answer:
Explanation:
= 250 moles.
N = n×6.02×
= 1.505×
Total charge = (1.505×) × (1.6×)
= 2.4× C.
Answer
given,
mass of the ball = 300 g
= 0.3 Kg
maximum altitude of the ball = 10.1 m
Potential energy of the softball:
PE = m g h
PE = 0.3 x 9.8 x 10.1
PE = 29.69 J
Maximum kinetic energy at which the ball is released from hand to reach height of 10.1 m is 29.69 J.
Kinetic energy at which ball returns to your hand is equal to 29.69 J.
speed of the ball
v² = 197.93
v = 14.069 m/s
A muscle that assists the prime mover or helps stabilize the joint during movement would be a synergist.

Answer:
The average velocity of the entire trip is 42.5 mph east ⇒ answer C
Explanation:
The average velocity of an object is its total displacement divided by
the total time taken.
It is the rate at which an object changes its position from one
place to another.
It is a Vector quantity
A car travels 25.0 miles due east for one hour
Then it travels another 60.0 miles east for an additional hour
We need to find his average velocity of the entire trip
He is travels due east in the whole trip
The total displacement that he travels = 25 + 60 = 85 miles east
He travels the first part in 1 hour and the second part in another hour
The total time for the whole trip = 1 + 1 = 2 hours
The average velocity = total displacement ÷ total time
His average velocity = 85 ÷ 2 = 42.5 miles/hour east
<em>The average velocity of the entire trip is 42.5 mph east</em>
newtons first law states that a object in motion will stay in motion unless acted on by an outside force and an object at rest will stay at rest for the same reason. the force of a moving object is equal to its mass times its acceleration.
