The acceleration of the box as it slides down the ramp is 4.9 m/s².
<h3>
What is the acceleration of the box down the incline?</h3>
The acceleration of the box down the incline is determined by applying Newton's second law of motion as shown below;
F - Ff = ma
where;
- F is the parallel force on the box
- Ff is the frictional force on box = 0
- m is the mass of the box
- a is the acceleration of the box
F - 0 = ma
F = ma
mg sinθ = ma
g sinθ = a
where;
- g is acceleration due to gravity
- θ is the angle of inclination of the incline
a = 9.8 x sin(30)
a = 4.9 m/s²

Answer:
D. all sounds are caused by vibrations
Explanation:
Answer:
38.77 kg
Explanation:
The weight of an object is given by:
Weight = mg, g = acceleration due to gravity ( 9.8 m/s square)
and m is the mass.
So, in this case:
Weight of dog is 382 N, so, by putting the values of weight and g into the equation we will get the mass of dog.
382 = mass multiply with 9.8
so, the mass of the dog will be 38.77 kg
One way you could think about it is that you used science of electronics to develop the technology of a computer

The exact same amount of force will be exerted but in opposite direction
