Given that,
Mass of the object, m = 1 kg
It moves in a circle of radius 0.5 m with a speed of 5 m/s
To find,
The direction of the acceleration.
Solution,
Whenever an object moves in a circular path, the only force that acts on its is centripetal force which is given by the formula as follows :
The centripetal acceleration acts in the direction of force. It acts along the radius of the circular path. In this figure, the direction of the acceleration is shown at point d.
Light because it is an electromagnetic wave and they can travel through the vacuum in outer space.
Explanation:
The given data is as follows.
Mass of evaporating dish = 3.375 g
Total mass = Mass of solid sample + evaporating dish
That is, Mass of solid sample + evaporating dish = 26.719 g
Therefore, we will calculate the mass of solid sample as follows.
Mass of solid sample = (Mass of solid sample + evaporating dish) - mass of evaporating dish
= 26.719 g – 3.375 g
= 23.344 g
Thus, we can conclude that mass of his solid sample must be 23.344 g.
The temperature of the water and the and the salinity of water
When the temperature increases the volume will increase, and when it cools it will decrease. This is because the molecules spread further apart as the temp gets higher, which creates a bigger volume.
