Answer: 1.d) The acceleration of an object is always less than the acceleration due to gravity, g (9.81m/s^-2)
2.a)acceleration decreases
Explanation:
Newton's second law:
Newton's second law states that the acceleration of an object is defined by two variables which is the total force acting on the object and the mass of that object. The acceleration is directly proportional to the net force that is applied on an object and inversely proportional to the mass of that object.
When the force applied on an object is increased so does the acceleration of an object however if the mass increase the acceleration decreases.
This can be felt when you look at the truck which usually carry heavy loads they seem to drive slow due to the load hence their acceleration is decreased by the mass that these truck carry .
Answer:
The Electric flux will be
Explanation:
Given
Strength of the Electric Field at a distance of 0.158 m from the point charge is
We know that the flux of the Electric Field can be calculated by using Gauss Law which is given by
Let consider a sphere of radius 0.158 m as Gaussian Surface at a distance of 0.158 m from the point charge and Let be the flux of the Electric Field coming out\passing through it which is given by
It can be observed that same amount of flux which is passing through the Gaussian sphere of radius 0.158 is also passing through the Gaussian sphere of radius 0.142 m at a distance of 0.142 m from its centre.
Also it can be observed that the charge inside the two Gaussian Sphere mentioned have same value so the Flux of electric field through them will also be same.
So the electric flux through the surface of sphere that has given charge at its centre and that has radius 0.142 m is
<span>a force that does not involve physical contact between two objects ic called field force.</span>
There is no similarity between the two situations aside from the fact that the earth will still be under the gravitational pull of the sun. Whatever the position of the earth around the sun, the gravity never looses its connection to it. But there are some incidents that might happen to the life forms of the earth if incase the earth stops rotating, all life forms not rooted on the ground will be pulled of moving eastward at 1000mph. Aside from that, an entire earth day will be equivalent to one year. The sun will also rise on the west and sets on the east. The earth's centrifugal force will also be changed causing the earth's structure to bulge. These things will happen if incase the earth stops rotating.
Answer:
A kg of cotton is heavier.
Explanation:
Because in air, cotton gets upthrust that's why weighing machine gives less weight than its actually have.
for eg: If cotton has 800g weight, the machine shows a kg(1kg) when measure in air due to upthrust.
I hope this will be helpful for you.
