Answer:
2.5 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity.
The S.I unit of acceleration is m/s²
For circular motion, the expression for acceleration is given as,
a = ω²r ................ Equation 1
Where a = acceleration of the particle, ω = angular speed of the particle, r = radius of the circular path.
Given: ω = 5 rev/s = 31.42 rad/s, r = 0.10 m.
Substitute into equation 1
a = 5²(0.10)
a = 25(0.10)
a = 2.5 m/s²
Hence the acceleration of the particle = 2.5 m/s²
Hence, none of the option is correct
Answer:
4 m/s^2
that is the right acceleretion a car
Answer:
311,850 N
Explanation:
We can solve the problem by using Newton's second law:
where
F is the net force exerted on the object
m is the mass of the object
a is the acceleration
In this problem, we have
m = 27 kg is the mass
a = 11,550 m/s^2 is the acceleration
Solving for F, we find:
Answer:
nuclear fusion
<h3>The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.</h3>
