all the allials must be aligned in the same direction
magnets are affected by heat, drops, and improper storage
Mass per cubic metre so kg/m3. Temperature may give different results.
Answer:
Heat required = mass× latent heat Q = 0.15 × 871 ×
Answer:
magnitude of gravitational force between the Earth and the Sun at B is greater than that at A
Explanation:
Formula of gravitational force:
F = GMm/r^2
(r is the distance between 2 objects)
We see that r(B) < r(A) since at B, the Earth is closer to the Sun than at A
According to the Formula, the smaller r is, the greater F is
So, F(B) > F(A)
