Answer:

A. Capitalist economy

Explanation:

The United States is a capitalist economy. Hope this helps, thank you !!

Answer:

See explanations below

Explanation:

1) KE = 1/2mv²

mass m = 0.142kg

v = 40m/s

KE = 1/2 * 0.142 * 40^2

KE = 1/2 * 0.142 * 1600

KE = 800*0.142

KE = 113.6Joules

2) KE = 1/mv^2

KE = 196

mass m = ?

velocity v = 52m/s

Substitute

196 = 1/2*m*52²

196 = 1352m

m = 196/1352

m = 0.145kg

Hence the mass of the baseball is 0.145kg

3) KE = 1/2mV^2

288 = 1/2 * 4v²

288 = 2v²\

v² = 288/2

v² = 144

v = 12m/s

The velocity of the shotput is 12m/s

Answer:

1) It expresses the rate (top speed) at which it can move with time.

2) P = 20 W

3) h = 18 km

Explanation:

1) Power is the rate of transfer of energy.

⇒ Power = [tex]\frac{Energy(or workdone)}{Time}[/tex]

i.e P = [tex]\frac{E}{t}[/tex]

Thus a car's engine power is 44000W implies that the engine of the car can propel the car at this rate. This expresses the rate (top speed) at which it can move with time.

2) m = 400g = 0.4 kg

    t = 20 s

h = 100m

g = 10 m/[tex]s^{2}[/tex]

P = [tex]\frac{mgh}{t}[/tex]

  = [tex]\frac{0.4*10*100}{20}[/tex]

  = [tex]\frac{400}{20}[/tex]

P = 20 W

3) u = 600 m/s

   g = 10 m/[tex]s^{2}[/tex]

From the third equation of free fall,

[tex]V^{2}[/tex] = [tex]U^{2}[/tex] - 2gh

V is the final velocity, U is the initial velocity, h is the height.

0 = [tex](600)^{2}[/tex] - 2 x 10 x h

0 = 360000 - 20h

20h = 360000

h = [tex]\frac{360000}{20}[/tex]

  = 18000

h = 18 km

The maximum height of the bullet would be 18 km.

Answer:

thermal

Explanation:

Answer:

Moonlight; phases; eight; 29 days; sunlit; earth; sun; moon.

Explanation:

A moon generally do not have or possess light but rather it reflects the light from the sun.

The moon is lit by light bouncing off of it. That light reaches Earth as moonlight. The different shapes that the moon appears to have are called phases. The moon goes through eight (8) phases as it revolves around the earth every 29 days. The phase that we see depends on how much of the sunlit part of the moon we can see. This depends on the positions of the earth, sun, and moon.

The eight (8) phases of the moon include the following;

1. Last quarter half moon.

2. Waning crescent moon.

3. New moon.

4. Waxing crescent moon.

5. First quarter half moon.

6. Waxing Gibbous moon.

7. Full moon.

8. Waning Gibbous moon.

Explanation:

The ball is pulling the spring down so this must be the direction of the force

Answer:

735watts

Explanation:

Power = Force*distance/time

Given

Force = mg = 50 * 9.8'

Force = 490N

distance = 3m

time = 2s

Substitute

Power = 490*3/2

Power = 1470/2

Power = 735Watts

Hence the minimum power output is 735watts

Answer:

a balanced force acted on it and propelled it to 4,000 km/hr

Explanation:

For the neutrons star which is moving in outer space at 4,000 km/hr, it could only be possible as a result of the balanced force which had already acted on it. This is based on newton's law of motion which states that 'To every action, there is equal and opposite reaction'.

Answer:

Explanation:

Answer:

Unbalanced forces cause acceleration.

Explanation:

They cause acceleration because one force is less or more in Newtons than the other force.

For example, let's say we have a cardboard box on the floor with no friction.

If one force is pushing the box to the right with 50 Newtons, and the second force is pushing the box to the left with 0 Newtons, the box would accelerate to the RIGHT because the forces are UNBALANCED.

Answer:

When evaluating synthetic blends, it's helpful to define the terms “synthetic blend” and “semi-synthetic”. Generally speaking, synthetic blends and semi-synthetic refer to the same thing: an oil that uses a combination of conventional and synthetic base oils in its formulation.

Explanation:

Answer:

Explanation:

Formula

F = m * a

Givens

F = 4900

a = 7 m/s^2

Solution

4900 = m * 7         Divide by 7

4900/7 = m

700 kg = m

Answer:

0.00339905404

Explanation:

kg: 0.00339905404

pascals: 333.333333

pounds: 0.0483459126

==>  The total mass resting on the table is (5 kg + 3 kg) = 8 kg.

==>  The total weight of that mass is (8 kg) x (9.8 m/s) = 78.4 newtons

==>  The boxes are stacked.  So the table doesn't know if the weight on it is coming from one box, 2 boxes, 3 boxes, or 100 boxes in a stack.  The table only knows that there is a downward force of 78.4 newtons on it.

==>  The table stands in a Physics classroom, and it soaks up everything it hears there.  It knows that every action produces an equal and opposite reaction, and that forces always occur in pairs.  

Ever since the day it was only a pile of lumber out behind the hardware store in the rain, the table has known that in order to maintain the good  reputation of tables all over the world, it must resist the weight of anything placed upon it with an identical upward force.  This is the normal thing for all good tables to do, up to the ultimate structural limit of their materials and construction, and it is known as the "normal force".

So the table in your question provides a normal force of 78.4 newtons. (d)
