The speed of the star is 255 km/s
Explanation:
The kinetic energy of a body is the energy possessed by the body due to its motion. Mathematically:
where
m is the mass of the object
v is its speed
For the star in this problem, we have:
is the mass
is the kinetic energy
Therefore, the speed of the star is:
Which corresponds to 255 km/s

Magnetic fields and electric fields are similar on the basis of the forces and its application.
<h3>What is an electric field?</h3>
An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
Magnetic and electric fields have certain similarities, are as follows;
1. Both the electric force and magnetic forces are the non-contact forces.
2. Both acts between the two entity having certain mass.
3. Both have their respective ranges.
Hence, magnetic fields and electric fields are similar on the basis of the forces and its application.

Answer:
5 m/s 2
To
get the acceleration of a car, you need to know first the difference in the
change in speed of a car then divided by time of the change. This can be
expressed as acceleration =
(change in speed) divided by (time for the change). So 30 m/s minus 10 m/s is
equal to 20 m/s divided by 4 seconds and the quotient is 5 m/s2.
Answer:
Explanation:
We have given volume V =
We have to convert this volume into
We know that 1 m = 3.28 feet
So for converting to we have to multiply to 1.5
So
So in cubic meter 1.5 will be equal to 82.923 cubic feet
