Answer:
Explanation:
The first equation of motion given as,
v = u +at
Here, u is initial and v is final velocity and a is acceleration and t is time taken.
As per question car initial velocity, u = 90 m/s, final velocity, v =0 and time taken, t = 3.00 s.
Substituting these values in first equation of motion, we get
0 = 90 m/s + a×3.00 s
or,
Thus, the deacceleration of the car is
I don’t really understand the question but if you are asking if matter can be found in different states of matter then yes
Given:
m = 0.32 kg
v = 11.5 m/s
To find:
1) Kinetic energy = ?
2) Work needed to stop the ball = ?
Formula used:
1) Kinetic energy =
2) Work = kinetic energy
Solution:
1)
Kinetic energy is given by,
Kinetic energy =
K.E. =
K.E. = 21.16 Joule
Thus, option (d) is the correct answer.
2)
Work needed to stop the ball is same as the kinetic energy because energy is the capacity to do work. Since, work is opposing the movement of the ball. Thus, Work = - Kinetic energy
Work = -21.16 Joule
The object has to move!
Thanks and Rate!
The answer yo this question is:
B-"Nitrogen, Arsenic, and Antimony"
Because its the only one out of all of the rest of the list that it contain properties that have similar element
