Answer:

a = 0.50 m/s²

v = 6.0 m/s

Explanation:

Step 1: Given data

  • Initial velocity (u): 0 m/s (rest)
  • Displacement of the marble (s): 36 m
  • Time elapsed (t): 12.0 s
  • Final velocity (v): ?
  • Acceleration (a): ?

Step 2: Calculate the acceleration

We will use the following suvat equation.

s = u × t + 1/2 × a × t²

s = 0 × 12.0 s + 1/2 × a × (12.0 s)²

36 m = a × 72.0 s²

a = 0.50 m/s²

Step 3: Calculate the final velocity

We will use the following suvat equation.

v = u + a × t

v = 0 + 0.50 m/s² × 12.0 s

v = 6.0 m/s

Do you support trucks are identical each box loaded on the truck has the same mask choose the truck that has the greatest force
Anestetic [448]

gravitational force of earth is given by

F = mg

so here the force will depend on the product of mass and gravity

so here force will be more if we took the condition of more masses

so here in 3rd figure

there will be maximum force of gravity on it

because it will have 6 boxes so there will be maximum mass

So figure of truck with 6 boxes on it is correct answer

Which of the angles shown in this picture is the angle of incidence?<br> A<br> B
Dmitry_Shevchenko [17]
The pictures are not attached, therefore, I cannot give a specific choice.
However, I will try to help you out.

The angle of incidence is defined as the angle formed between the ray of light and the normal to the surface that the ray is falling on.

The angle of incidence can be shown in the attached image.

Therefore, for your question, choose the image on which the above description applies.

Hope this helps :)

What is the equivalent resistance of the circuit?
Ivanshal [37]

Answer:

Since the wire is not splitting at any point in the circuit,

the resistors are in series

Hence, Equivalent resistance = 10 + 20 + 30

Equivalent Resistance = 60 Ω
