Answer:
Explanation:
Speed of car =22.5miles/hr
U=22.5miles/hour
Applied brake and come to rest
Final velocity, =0
t, =2sec
Given that,
Speed=distance /time
Then,
Distance, =speed, ×time
Converting mile/hour to m/s
Given that
Use: 1 mile= 1600 m, 1 h= 3600s
22.5miles/hour × 1600m/mile × 1hour/3600s
Therefore, 22.5mile/hour=10m/s
Using speed =10m/s
Distance =speed ×time
Distance=10×2
Distance, =20m
The distance travelled before coming to rest is 20m.
Answer:
Explanation:
The electron is the particle that rotates around the nucleus of the atom; it has a negative electric charge equal to :
which is known as fundamental charge.
For an object containing N excess electrons, the total charge of the object is
In this problem, the number of excess electrons in the object is:
Therefore, by plugging it the numbers, we can find the value of Q, the total charge of the object:
Answer:
D. momentum
Explanation:
Momentum is the product of velocity and mass which is the two variables the paragraph talked about.
The sun's energy flow through the earth's system by it moving through the earth's atmosphere.
