Answer:
The right leg (oil on top) is higher
Explanation:
Given:
The mass density of oil is lesser than the mass density of water.
- When we pour water in a u-tube that is open at both the ends then the water on both the sides of the tube will rise up to the same height because the algebraic sum of the pressure exerted by the water column and the pressure of atmosphere on both the openings is equal.
- When we pour oil in the right side of the u-tube we observe that the column of liquid on the right side rises more than the column of the liquid on the left side. However we observe that there is rise on both sides of the u-tube.
<u>This is justified by the equation:</u>
where:
density of the liquid
acceleration due to gravity
height of the liquid column
Answer:
When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces.

Answer:
<u><em>1000 units for breakeven</em></u>
Explanation:
Let x be the number of units sold at breakeven.
The total sales at the point would be $2x.
Variable costs would be $1x and fixed costs are $1000.
Total costs are = $1x + $1000
At breakeven: Sales = Costs
Sales =m Costs
$2x = $1x + $1000
$1x = $1000
x = 1000 units.
At 1000 units the sales are equal to the costs ("breakeven").
Answer:
A longitudinal wave is a wave where the movement of the medium is in the same direction as the wave. On the other hand, a transverse wave is a wave where the movement of the medium is at a right angle to the wave direction.
