Change the following data into scientific notation. 5 000 000 km

1 answer:

8 0

To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000.

Identify the equation used to calculate the perpendicular force (F⊥) acting on a block on an inclined plane.

pychu [463]

Using geometrical arguments, we can see that the angle of the inclined plane $\theta$ is equal to the angle between Fg and the perpendicular force.

But the perpendicular force is the projection of Fg along the perpendicular axis, and Fg=mg, so the correct answer is
C) F=mg cosΘ

A 0.54 kg particle has a speed of 5.0 m/s at point A and kinetic energy of 7.5 J at point B. What is

Wewaii [24]

Answers

(a) 6.75 Joules.

(b) 5.27 m/s

Explanation

Kinetic energy is the energy possessed by a body in motion.

(a) its kinetic energy at A?

K.E = 1/2 mv²

= 1/2 × 0.54 × 5²

= 6.75 Joules.

(b) its speed at point B?

K.E = 1/2 mv²

7.5 = 1/2 × 0.54 × V²

V² = 7.5 ÷ 0.27

= 27.77778

V = √27.77778

= 5.27 m/s

Work done = 7.5 - 6.75

= 0.75 Joules
