2. This diagram represents a top-down view of an experiment on a table. The 250 g and 100 g masses are falling and are pulling t
he block. Draw an arrow to show which way the block will move. You do not have to interpret the size of the arrow, just draw the direction.

Answer:
According to the data given in the question, experiment on table two pulling and falling masses are arranged in the fig. 250 g is pulling right side and 100 g pulling down. The gravitational force is common to both the masses, so we cannot say that the block moves towards heavier mass, also the block does not move towards the lighter mass.
Obviously, the effect of heavier mass of 250 g is more on the block, so the block moves towards right bottom corner. i.e., diagonally between two masses

Answer:
40 s
Explanation:
After 10 seconds, the first skater would have a 8m/s * 10s = 80 m head start
Let t be the number of seconds after the second skater starts will the second skater overtake the first skater
The distance traveled by the first skater after t seconds is
Similarly the distance traveled by the 2nd skater after t seconds is
Since the 2nd skater catches up to the 1st one after 80 m behind, the distance traveled by the 2nd one must be 80m greater than the distance of the 1st skater
We can substitute

Explanation:
Assuming the liquid to be water ,
the density of water is :
Buoyant force exerted by a liquid on an object with of it's volume immersed is :
where ,
is the buoyant force
is the density of the liquid
is the acceleration due to gravity
Thus at equilibrium:
from these , we get the density of brass to be
which is not possible
