The triceps muscle in the back of the upper arm is primarily used to extend the forearm. Suppose this muscle in a professional b

bagirrra123 [75]

To solve this problem it is necessary to address the concepts related to Torque as a function of the force and distance where it is applied and the moment of inertia from which the torque, moment of inertia and angular acceleration are related.

By definition the torque is defined as

$\tau = F*r$

Where,

$\tau = Torque$

F = Force

r = Radius

For our values we have:

$\tau = F*r$

$\tau = (1.75*10^3)(2.8*10^{-2})$

$\tau = 49Nm$

Consequently the calculation of the moment of inertia would then be given by the relationship

$\tau = I\alpha$

$I=\frac{\tau}{\alpha}$

Replacing with our values

$I = \frac{49}{150}$

$I = 0.322Kg.m^2$

The moment of inertia of the boxer's forearm $0.322Kg.m^2$

A U-shaped tube open to the air at both ends contains water. A quantity of oil of unknown density is slowly poured into the righ

nadezda [96]

Answer:

$\rho_o=600\ kg.m^{-3}$ is the density of the oil

Explanation:

Given:

height of oil column, $h_o=20\ cm$

oil column height that is more than the water column height in the other arm, $\delta h=8\ cm$

Now from the given it is clear that the height of water column is:

$h_w=h_o-\delta h$

$h_w=20-8$

$h_w=12\ cm$

Now according to the pressure balance condition of fluid columns:

Pressure due to water column = Pressure due to oil column

$P_w=P_o$

$\rho_w.g.h_w=\rho_o.g.h_o$

$1000\times 9.8\times 0.12=\rho_o\times 9.8\times 0.2$

$\rho_o=600\ kg.m^{-3}$ is the density of the oil

The value of the speed of the car, for the front glass of the car to get wet, $V_c \geq 10 \ m/s$ .

The given parameters:

Speed of the car, = Vc
Speed of the rain, = 10 m/s

The relative velocity of the car with respect to the falling rain is calculated as;

$V_{C/R} = V_C- V_R$

If the speed of the car equals the speed of the rain, the rain will fall behind the car.
If the speed of the rain is greater than speed of the car, the rain will fall far in front of the car.
If the speed of the car is greater than speed of the rain, the rain will fall on the car.

Thus, for the front glass of the car to get wet, $V_c \geq 10 \ m/s$ .
