It’s due in like 2 hour!! 1. A force of 52N acts upon a 4kg block sitting in the ground. Calculate the acceleration of the object (show work)

2. An object of mass 10kg is accelerated upward at 2 m/s^2. What force is required? (Show work)

3. What is the mass of an object if a force of 17N caused it to accelerate at 1.5m/s^2? (Show work)

1. Acceleration = 6.25 m/s²

2. Force = 20 Newton.

3. Mass = 11.33 kg

Explanation:

Given the following data;

1. Force = 25N

Mass = 4kg

To find the acceleration;

Acceleration = force/mass

Acceleration = 25/4

Acceleration = 6.25 m/s²

2. Mass = 10kg

Acceleration = 2 m/s²

To find the force required;

Force = mass * acceleration

Force = 10 * 2

Force = 20 Newton.

3. Force = 17N

Acceleration = 1.5 m/s²

To find the mass;

Mass = force/acceleration

Mass = 17/1.5

Mass = 11.33 kg

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

i think the answer would be b
