The space shuttle orbits 310 km above the surface of the Earth.
1 answer:
Answer:
44.7 N
Explanation:
The gravitational force between the objects is given by:
where
G is the gravitational constant
m and M are the masses of the two objects
r is the distance between the centres of the two objects
In this problem, we have:
is the mass of the sphere
is the Earth's mass
is the Earth's radius, while h=310 km is the altitude of the sphere, so the distance of the sphere from Earth's centre is
Substituting into the equation, we find

Answer:
Explanation:
Given that :
The current I = 8.6 A
The length vector L = 2.3 m i
The force vector is = -2.0 j N
When L = 2.3 m i ; the
Force vector F = (2.0 i - 4.8 k) N
Compute the components of the magnetic field as follows:
Replacing 8.6 A for I ; -2.0 j N for F & 2.3 m i for L
However in y direction ; we have :
Hence, the component of magnetic field is as follows:
Ticker Tape analysis is a common way of analyzing the motion of the objects to perform in the physics laboratory. A long tape is attached to a moving object and threaded through a device that places a tick upon the tape at regular intervals of time. This ticker tape can also determine if the object is fast or slow. It can also reveal if the object is moving with a constant velocity or accelerating. The changing velocity and acceleration represented by the changing distance between dots in the ticker tape. And also the constant velocity and therefore no acceleration represent the constant distance between dots.
