Answer:
Polar bears (Ursus maritimus) are of special interest because of their large size, white color and position as the top-level carnivore in the remote arctic environment. They occur only in the northern hemisphere nearly always in association with sea ice. They have only two colors of fur: tan and white. Polar bears were created to withstand cold temperatures and are quite adaptable. Polar bears are ferocious and the most dangerous of bears. They can lop a person's head off with one swoop of their paw.
The momentum should be .5 because you multiply the mass and velocity to get momentum
Net work done on student B by the Ferris wheel in moving from the top to the bottom is mathematically given as
net work done on A =0.
<h3>
Net work done </h3>
Generally the equation for the work energy theorem is mathematically given as
net work done on A = change in kinetic energy of A.
Where, angular velocity is constant.
change in kinetic energy = 0.
Hence, from work energy theorem,
net work done on A =0.

Answer:
The torque needed is 46.08 Nm
Explanation:
Given;
angular velocity, ω = 12 rad/s
time of motion, t = 0.5 s
length of the baton, r = 0.8 m
mass of the baton, 0.5 kg
The torque needed to reach the angular velocity is given by;
τ = F x r
where;
F is the centripetal force of the baton
r is the length of the baton = radius of the circular motion of the baton

Torque is given by;

Therefore, the torque needed is 46.08 Nm
