GREYUIT [131]3 years ago

Answer:

Acceleration will 7.5 times g = 7.5 g

Explanation:

Centripetal acceleration is given by a = v²/r.

The speed in m/s will be; (96.6 Km/h )÷ 3.6

                                        = 26.83 m/s.

Centripetal force = v²/r

                            = 26.83²/9.80

                            = 73.454 m/s²

But; g = 9.8 m/s²

Therefore the acceleration in terms of g will be;

  = 73.454/9.8

   = 7.5 g

Acceleration is 7.5 g

you ride a bike for 2 hours at 25 km/hr then 3 hours at 34 km/hr. what is your average velocity (in km/hr)?
mamaluj [8]
<h3>Answer:</h3>

30.4 km/hr

<h3>Explanation:</h3>

<u>We are given</u>;

  • Speed in the first 2 hours as 25 km/hr
  • Speed in the next 3 hours as 34 km/hr

We are required to determine the average velocity in km/hr

  • To get the average velocity we divide total distance by total time.
  • Thus, we need to determine the total distance

Distance = Speed × time

Distance covered in the first 2 hours;

               = 25 km/hr × 2 hours

               = 50 km

Distance in the next 3 hours

                = 34 km/hr × 3 hours

                = 102 km

Therefore, total distance = 50 km + 102 km

                                        = 152 km

Total time = 2 hrs + 3 hrs

                = 5 hours

Therefore;

Average speed = 152 km ÷ 5 hours

                          = 30.4 km/hr

Thus, the average speed is 30.4 km/hr

Two metal spheres are made of the same material and have the same diameter, but one is solid and the other is hollow. If their t
galina1969 [7]

Answer:

D) the two spheres remain of equal size.

Explanation:

  • Since the body of the sphere is made up of both the same material. Thus the orientation will not affect the expansion. That is solid upon solid and hollow upon the hollow sphere. Hence it can be said that both the sphere expands and is due to the material used for making both of them is the same.

DochEvi [55]

Answer:

1) The angle of deflection will be less than 45° ( C )

2)  The angle of deflection will be greater than 45° but less than 90° ( E )

Explanation:

1) Assuming that the force applied  has a direction which is perpendicular to the Earth's magnetic field

∴ Fearth > Fapplied   hence the angle of deflection will be < 45°

2) when the Fearth < Fapplied

the angle of deflection will be :   > 45°  but  < 90°
