When unbalanced force is acting on the system of mass then as per Newton's II law we can say
here we have
now since the force and mass both given to us so we can find acceleration of object from this
now when 50 N force is applied on a box then this 50 N force is unbalanced force on it and it will produce acceleration to the box
So here we can say that box will accelerate with constant acceleration and hence its velocity will linearly increase with time.
Now the displacement of the object will be given as
so here the displacement will be a quadratic function of time and increases with time as well
so here overall the motion will be of constant acceleration, uniformly increasing velocity and displacement will be a quadratic function of time
Answer:
Now make holes in all the directions. Now fill with water. The water comes out of the bottle in all the direction. This shows that liquids exert pressure in all direction
Answer:
See the answer below
Explanation:
If you step on the brake of a car while driving, the frictional force between the tires of the car and the surface of the road increases in opposition to the motion of the car. Consequently, the car slows down.
If you release your foot from the brake pedal when the car is still at half speed, the frictional force reduces and the car speeds up a bit even without pressing the throttle. Eventually, the frictional force will slow down and stop the car if the throttle is not pressed.
Answer:
Radio waves have frequencies as high as 300 gigahertz(GHz)to as low as 30 hertz(Hz).At 300 GHz the corresponding wavelength is 1mm and at 30Hz is 10,000 km
Density can be defined as the measure of mass of a substance per unit volume.
