Answer:

60 kg

Explanation:

The man's weight is equal to the weight of the water he displaces.

mg = ρVg

m = ρV

m = (1000 kg/m³) (3 m × 2 m × 0.01 m)

m = 60 kg

The man's mass is 60 kg.

When observing the two diagrams, what is a concept shared by both?​
Wewaii [24]

Answer:

Convection

Explanation:

Convection refers to the transfer of heat by the actual movement of the heated molecules from the hot parts to the cooler parts.

Thus, the two diagrams show illustrate transfer of heat by the movement of molecules of a fluid.

This mode of heat transfer is known as convection. It is the concept illustrated by both diagrams.

Which gives the work done by a torque during angular displacement?
Nutka1998 [239]

Only when the torque is constant the work done is done during angular displacement. So the correct option is d.

Work done by the force is calculated as the dot product of force and  angular displacement of the point of application of force. It is equal to the change in rotational kinetic energy of the body.

Work done by a torque can be calculated by taking an analogy from work done by force.

Work done = torque × angular displacement

So work is done by a torque during angular displacement only when torque is constant.

If a torque applied on a body rotates it through an angle ω, the work done by torque is

W = ζ × ω

To know more about the work done by torque refer to the link given below:

Outside my window a squirrel is scurrying up and down a tree. Its position function is given by s(t) = t 3 − 12t 2 + 36t for the
marin [14]

Answer:

Explanation:

Given

Position of squirrel is given by

s(t)=t^3-12t^2+36t

Velocity is given by

v(t)=\frac{ds(t)}{dt}=\frac{d(t^3-12t^2+36t)}{dt}

v(t)=3t^2-12\times 2t+36

v(t)=3t^2-24t+36

(b) acceleration is given by

a(t)=\frac{da(t)}{dt}=\frac{d(3t^2-24t+36)}{dt}

a(t)=6t-24

(c)at s(3)=3^3-12(3)^2+36(3)

s(3)=27\ m

at s(4)=4^3-12(4)^2+36(4)

s(4)=16\ m

at t=3\ s Position is 27\ m and at t=4\ s position is 16\ m

therefore squirrel is moving down
