What is atmospheric pressure?

1 answer:

8 0

"Atmospheric pressure" is the pressure of the air outside the body.
One result of atmospheric pressure is that all living things are built
so that the pressure INSIDE the body is the same as atmospheric
pressure. This arrangement neatly avoids our becoming squished
by the pressure outside and all around us.

Four point masses of 3.0 kg each are arranged in a square on masslessrods. The length of a side of the square is 0.50m. What is

Zigmanuir [339]

Answer:

Part a)

$I = 1.5 kg m^2$

Part b)

$I = 0.75 kg m^2$

Part c)

$I = 1.5 kg m^2$

Explanation:

Part a)

Moment of inertia of the system about an axis passing through B and C is given as

$I = mL^2 + mL^2 + m(0) + m(0)$

$I = 2mL^2$

$I = 2(3 kg)(0.50^2)$

$I = 1.5 kg m^2$

Part b)

Moment of inertia of the system about an axis passing through A and C is given as

$I = m(0^2) + m(\frac{L}{\sqrt2})^2 + m(0) + m(\frac{L}{\sqrt2})^2$

$I = 2m\frac{L^2}{2}$

$I = (3 kg)(0.50^2)$

$I = 0.75 kg m^2$

Part c)

Moment of inertia of the system about an axis passing through the center of the square and perpendicular to the plane of the square

$I = m(\frac{L}{\sqrt2})^2 + m(\frac{L}{\sqrt2})^2 + m(\frac{L}{\sqrt2})^2 + m(\frac{L}{\sqrt2})^2$

$I = 4m\frac{L^2}{2}$

$I = 2(3 kg)(0.50^2)$

$I = 1.5 kg m^2$

Construction, principal and working of electric motor

bogdanovich [222]

A power supply A basic motor has a DC power source, in general. It supplies power for the motor or field coils armature. Field Magnet can be a permanent magnet or electromagnet The magnetic field tends to generate a torque on the spinning armature coil by virtue of Fleming's lefthand rule.

If there is no friction in a rollercoaster is the speed the same throughout?

andrey2020 [161]

If there is no friction, the roller coaster would keep moving forever but a constant velocity. The only way it would accelerate is if there was a force continually pushing on it.
