Answer:
-1000 N
Explanation:
First calculate the acceleration:
v² = v₀² + 2a(x - x₀)
(0 m/s)² = (100 m/s)² + 2a (0.05 m)
a = -100,000 m/s²
Now calculate the force:
F = ma
F = (0.010 kg) (-100,000 m/s²)
F = -1000 N
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:
Due to the direction of force due to pressure.
Explanation:
Let there be two small holes having area, , at points A and B in the bottle filled with water as shown in the figure . Water comes out at the right angles to the wall of the bottle as shown in figure .
From Newton's second law, the acceleration of an object is always in the direction of net applied force.
We know that pressure, , on any surface due to fluid acts perpendicular to the surface, so, the force due to pressure,, will also be perpendicular to the surface as shown in the diagram.
So, the direction of the acceleration of the water element at that point will be perpendicular to the bottle surface which leads to the change in velocity of the water element in the same direction.
That's why water comes out at right angles to the surface of the bottle.
The weight of an object is given by:
where m is the mass and g is the gravitational acceleration.
Miguel's mass is the same on every planet (m=60 kg), the only element changing in the formula is g, the value of the gravitational acceleration, which is different for every planet. So by knowing the ratio , where g is the gravitational acceleration on Earth and is the value of the gravitational acceleration on the planet we are studying, we can calculate the ratio , where W is Miguel's weight on Earth (which we know, it is W=132 lbs), and Wx is the weight on the planet we are studying:
- For the Moon, we have
so the weight on the Moon is
- For Neptune, we have
so the weight on Neptune is
- For Mercury, we have
so the weight on Mercury is
Answer:
