The famous black planet, haunch, has a radius of 106 m, a gravitational acceleration at the surface of 4 m/s2 , and the tangenti
statuscvo [17]
Gravity on the surface = 4 m/s^2
Now, the acceleration due to centripetal motion, a = v^2/R

Where,
v= 10^3 m/s, R = 10^6 m
Then,
a = (10^3)^2/(10^6) = 1 m^2/s

The net gravitational acceleration = 4-1 = 3 m/s^2

The reading on the spring scale = ma = 40*3 = 120 N

What happens to the negative charges
Nikitich [7]

Answer:

<em>The correct option is C) spreads out over a large area on the object. </em>

Explanation:

In physics, a ground can be described as a reservoir object in which charge can be stored. Grounding refers to the removal of charge in an object by using the ground object. When an object with excess if charge is placed on the ground object, the electrons are transferred from the charges object to the ground object. This charge begins to spread evenly in the ground object with the passage of time.

Which law describes the magnetic field in a nonlinear wire? A. Faraday's law B. Gauss's law C. Ohm's law D. Ampère's law
Korolek [52]

Answer:

B. Gauss’s law

Explanation:

Gauss’s law is defined as the act of thinking something carefully, careful thought; meditation; deliberation. consideration acts like filter on the information a person receives, because it allows them to contemplate the implications of something before acting on it.

Two identical masses are attached to two identical springs that hang vertically. The two masses are pulled down and released, bu
Alex17521 [72]

Answer:

Lets take mass of A = m

Mass of B = m

Lets take spring constant = K

Displacement of mass A = x

Displacement of mass B= x'

Given that

x ' > x

a)

We know that time period of spring mass system given as

T= 2\pi\sqrt{\dfrac{m}{K}}

Time does not depends on the displacement.

So time will be same for both.

b)

We know that acceleration given as

a= ω² .x

ω=natural frequency  (  ω² = m K)

Here   x ' > x

So Acceleration of mass B is greater than mass A.

c)

Velocity at  equilibrium position

V= ω .x

Here   x ' > x

So velocity of mass B is greater than mass A.

d)

As we know that at equilibrium point acceleration of the mass is zero.So both the mass have same acceleration and the value of this acceleration will be zero m/s².

Fluid clutches are used on equipment that is subjected to?
mamaluj [8]
Fluid clutches are used on equipment that is subjected to higher torque per unit volume. This type of clutch makes use of an incompressible fluid like oil in order to transfer the input of a movement from a pedal and cylinder to an actuating cylinder. Releasing the this clutch would stop the transfer of power but still allowing the engine to turn continuously.
