Answer:
Explanation:
For acceleration due to gravity g , the expression is
g = GM / R² , where G is gravitational constant M is mass of the earth and R is radius of the earth .
At height h , let the value of it becomes g / 4 , so
g / 4 = GM / ( R + h )²
dividing
4 = [( R+ h)² / R² ]
2 = (R + h) / R
2 = 1 + h / R
h / R = 1
h = R
So at height equal to radius of the earth , acceleration due to gravity becomes 1 /4 of value on the surface of the earth .
A toggle clamp is a device that you employ, often but not exclusively as part of a production process, to firmly place components or parts in place.
Explain about toggle clamp.
A toggle clamp's main characteristics are its rapid action and ability to be easily turned on and off by an operator. Toggle clamps also lock in place firmly. Because of this, toggle clamps are frequently employed in production lines where components need to be held firmly and quickly removed during routine manufacturing procedures.
Toggle clamps with standard or light action are often constructed from components of pressed steel that have been zinc-plated.
Depending on the setting in which you work, Stainless Steel is another alternative for Toggle Clamp production. Stainless steel toggle clamps are frequently used in regulated areas where hygiene is crucial, such as the food industry and the pharmaceutical business.

Answer:
(I). The motional emf induced between the ends of the segment is
(II). The motional emf is zero.
Explanation:
Given that,
Magnetic field = 0.080 T
Velocity of wire segment = 78 m/s
Component in x direction = 18 m/s
Component in y direction = 24 m/s
Component in z direction = 72 m/s
Length = 0.50 m
We need to calculate the motional emf induced between the ends of the segment
Using formula of emf
Put the value into he formula
(II). If the wire segment is parallel to the y-axis then the angle between B and v is zero.
We need to calculate the motional emf
Using formula of emf
Here,
Hence, (I). The motional emf induced between the ends of the segment is
(II). The motional emf is zero.
Answer:
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time.
Explanation:
Force = change of momentum / time taken
Force = (90x3)/0.6
