Answer:

a=1.46\ m/s^2

Explanation:

It is given that,

Mass of the cart, m = 45 kg

Net force acting on the cart, F = 66 N

Let a is the acceleration of the cart with which it is pushed. It can be calculated using Newton's second law of motion as :

F = m a

a=\dfrac{F}{m}

a=\dfrac{66\ N}{45\ kg}

a=1.46\ m/s^2

So, the acceleration of the cart is 1.46\ m/s^2. Hence, this is the required solution.

Answer:

A aceleração do carrinho é de, aproximadamente, 1,46 m/s².

Explanation:

F=ma

F: force

m: mass

a: aceleration

66 = 45a

a=66/45= 22/15 ≅ 1,4666 m/s²

When passing from a low index of refraction medium to a high index of refraction medium which way does the refracted ray bend: t
Vaselesa [24]

Answer:

toward the normal

Explanation:

Light travels at different speed in different mediums.

Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.

Or ,

n = c/v.

Light travels at a slower speed in water as compared to air because there are more number of interfering molecules in the path of the light in case of water as compared to liquid.  

When a light travels from lower denser medium say water to higher denser medium say water, it bends towards the perpendicular (normal) as its speed reduces in that medium.

Can a body have constant speed and still be acclerating ? Give an Example
Allushta [10]






Hi Pupil Here's Your answer :::

An object moving with constant speed can be accelerated if direction of motion changes. For example, an object moving with a constant speed in a circular path has an acceleration because its direction of motion changes continuously.
