Answer:

As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude

Answer:

White light contains yellow, green, and blue - only the blue light will be reflected giving the blue color.

So the green and yellow light thru the filter will not be reflected and the fabric will still appear blue.

blue is correct

Space telescopes must be placed in orbit around earth in order to observe short-wavelength radiation.

A telescope is an optical instrument that uses lenses, curved mirrors, or a combination of both to watch distant objects.

When atoms in a gas reach this temperature, they travel so quickly that when they collide, they release X-ray photons with wavelengths smaller than 10 nanometers.

Because the Earth's atmosphere prevents all X-rays from space, these wavelengths must be seen using space telescopes.

To study short-wavelength radiation, space telescopes must be put in orbit around the Earth.

Hence, space telescope is the correct answer.

Answer:

KE = F * S     initial kinetic energy will expended in stopping object

1/2 M V^2 = F * S

S = 1/2 * 50 * 35^2 / 800 = 38.3 m      stopping distance

If you need to know the stopping time involved -

(V2 - V1) = a t     where the change in velocity is 35 m/s

a = F / M = 800 / 50 = 16 m/s^2      deceleration of mass

t = 35 / 16 = 2.2 sec

The ball rolling without slipping will make it furthest up the ramp because it has greater kinetic energy.

The height rolled by each object can be determined by applying the principle of conservation of energy.

The ball rolling without slipping will have additional rotational kinetic energy.

The block won't have additional rotational kinetic energy.

Total K.E ball > Total K.K block

ΔP.E = ΔK.E

Thus, the ball rolling without slipping will make it furthest up the ramp because it has greater kinetic energy.

Answer:

Taking forces along the plane

F cos θ - M g sin θ -100 = M a       net of forces along the plane

F = (M a + M g * .5 + 100) / .866     solving for F

F = (80 * 1.5 + 80 * 9.8 * .5 + 100) / .866 = 707 N

F = 707 N acting along the plane

Fn = F sin θ + M g cos θ       forces acting perpendicular to plane

Fn = 707 * 1/2 + 80 * 9.8 * .866 = 1030 Newtons   forces normal to plane

(this would give a coefficient of friction of 100 / 1030 = .097 = Fn)

Answer:

9kg.

Explanation:

Data obtained from the question include:

F (force) = 45N

a (acceleration) = 5 m/s2

m (mass) =?

Force is simply the product of mass and acceleration as given by the formula: F = ma. With this formula (i.e F = ma) we can easily calculate the mass of the object. This is illustrated below:

F = ma

m = F/a

m = 45/5

m = 9kg.

Therefore, the mass of the object is 9kg

For a photocopier to work, a field of positive charges must be generated on the surface of both the drum and the copy paper. These tasks are accomplished by the corona wires. These wires are subjected to a high voltage, which they subsequently transfer to the drum and paper in the form of static electricity.

Answer:

  170 N

Explanation:

Impulse is the change in momentum. Momentum is the product of mass and velocity. These are related to applied force by ...

  F·Δt = m·Δv

Here, the velocity goes from 0 to 34 m/s in 0.0116 s. The mass is 0.058 kg. Filling in the given values, we have ...

  F(0.0116 s) = (0.058 kg)(34 m/s)

  F = 0.058×34/0.0116 kg·m/s² ≈ 170 N

The required force is 170 newtons.

Answer:

The energy efficiency represents the things you can do with some amount of energy, and if you can do more with less, than it reduces the energy consumption.

Explanation:

The answer to this question is actually very simple. Imagine that you use only the half of the energy you produce, an efficiency of 50%. Lets say you need 5kJ, so you would need to produce 10kJ, because you can consume only the half. Now, imagine you increase the efficiency, you use exactly what you can generate, (efficiency of 100%). In this case, if you needed only 5kJ you would need to generate only 5kJ.
