Answer:
Explanation:
Given,
initial angular speed, ω = 3,700 rev/min
=
final angular speed = 0 rad/s
Number of time it rotates= 46 times
angular displacement, θ = 2π x 46 = 92 π
Angular acceleration
Answer:
-0.1 Joules
Explanation:
Here, the kinetic energy of the spring and glider is conserved.
So, we get
KE of spring + Work done by friction = Change in momentum of glider
The work done by friction during that segment of motion is -0.1 Joules
The coals or wood embers that are used in fire walking have a low heat capacity. Sweat produced on the bottom of people's feet also helps form a protective water vapor. All of this together makes it possible, if moving quickly enough, to walk across hot coals without getting burned.
Answer:
the answer is A all the other ones do not even make sence or fit the situation. so A
Explanation:
Answer:
The electric potential is 15.23 V
Explanation:
Given;
charge Q = 8.473 nC = 8.473 x 10⁻⁹ C
position of the charge, r = 5 m
Coulomb constant is 8.98755 × 10⁹ N·m² /C²
Electric potential is given as;
Therefore, a charge of 8.473 nC uniformly distributed along the x-axis from −1 m to 1 m, the electric potential (relative to zero at infinity) of the point at 5 m on the same axis is 15.23 V.
