Answer:
t=L/
Explanation:
<u>solution:</u>
Let E be an observer, and B a second observer traveling with velocity as measured by E. If E measures the velocity of an object A as then B will measure A velocity as
= -
Applied here,
the walkway (W) and the man (M) are moving relative to Earth (E}, the velocity of the man relative to the moving walkway is
= -
,
The time required for the woman, traveling at constant speed relative to the ground, to travel distance L relative to the ground is
:
t=L/
Answer:
The weight of an object would be less on the moon than on the earth
Explanation:
Thus, our object has mass m both on the surface of the Earth and on the surface of the Moon, but it will weigh much less on the surface of the Moon because the gravitational acceleration there is a factor of 6 less than at the surface of the Earth.
When two permanent magnets are placed adjacent to each other then they will exert magnetic force on each other.
There are four fundamental forces in nature
1. Gravitational force
2. Electromagnetic force
3. Weak Nuclear force
4. Strong nuclear force
So here magnets will exert two fundamental forces on each other <u>Electromagnetic force and Gravity</u>
#2
mass is defined as the composition or amount of substance while we can define weight as gravitational force of earth of the given object
Now when we transport an object from surface of earth to space far away from any planet then the amount of substance or mass will not change while the weight of the substance will decrease to zero because there is no gravity at this position
So we can say
mass = constant and will remain same
Weight = mass * gravity = 0
<u>The weight of the object changes, the mass stays the same</u>
