Repeat the experiment to make sure it gives the same results.
Hope i helped ; )
Answer:
no. the moon has less of a gravitational pull. therefore it would weigh less than 40n.
Explanation:
Precisely 84% if the Earth is made of mantle.
Answer:
B
Explanation:
Judging from the shape of the lens, you already know that the lenses are concave rather than convex. This eliminates C and D. Concave lens produce a smaller and virtual image at any specified distance.

The jogger's average speed 1.03 m/s
<h3>
The Speed and the Velocity of a Particle in a Circle</h3>
The speed of a particle is a circle will always be constant while the velocity will not. That is, velocity varies.
Given that a jogger jogs around a circular track with a diameter of 275 m in 14.0 minutes. First convert the minutes to seconds
Given parameters are;
- Time t = 14 minutes = 14 x 60s = 840 s
Speed V = 2πr ÷ t
V = ( 2 × π × 137.5 ) ÷ 840
V = 863.9 / 840
V = 1.028 m/s
Therefore, the jogger's average speed 1.03 m/s approximately
