Why is there less air pressure at higher altitudes?Air at higher altitudes doesn't have as much air weighing down on it from above.

Air at higher altitudes is cooler and less turbulent.

The molecules in the air lose mass and are less effected by gravity, significantly lowering their weight

The warmer, lighter air rises bringing cooler heaver air to low altitudes.

Answers

Answer 1

Answer:

Answer:

As ailtitudes rises air pressure drops ...... As altitude increases , the amount of gas molecules in the air decreases - so the air becomes less dense than air nearer to the sea level. So there is less air pressure at high altitudes

Humpty Dumpty (12 kg) sat on a wall (2 m high). What was his potential energy, before his great fall? A. 235.2 J B. 235.2 N C. 24 J D. 246.1 W

Answers

I think it would be B. P.E.=mgh, the mass is 12g, gravitational force is 9.8, and the wall is 2 meters high, so multiply it all and get 235.2.

It would be 24J because there's no energy.

What is a caliper used for?to make a precise measurement of volume
to make a temperature measurement with low precision
to make a volume measurement with low precision
to make a precise measurement of length

Answers

Answer;

To make a precise measurement of length

Explanation;

Calipers are used to make a precise measurement of length such as diameters of circular solids, such as the diameter of a pipe.

All calipers may be used to take the same measurements, that is the inside, outside, depth and the step measurements.Those calipers such as vernier caliper that can be used to measure the external size of an object have a pair of jaws.
Vernier caliper is a type of caliper that is used to precisely measure outside dimensions such as length, width, or diameter.

a caliper is used to make a precise measurement of length within tubing or on nuts/bolts, or anything really

Water enters a baseboard radiator at 180 °F and at a flow rate of 2.0 gpm. Assuming the radiator releases heat into the room at a rate of 20,000 Btu/ hr., what is the temperature of the water leaving the radiator?

Answers

Answer:

Temperature of water leaving the radiator = 160°F

Explanation:

Heat released = (ṁcΔT)

Heat released = 20000 btu/hr = 5861.42 W

ṁ = mass flowrate = density × volumetric flow rate

Volumetric flowrate = 2 gallons/min = 0.000126 m³/s; density of water = 1000 kg/m³

ṁ = 1000 × 0.000126 = 0.126 kg/s

c = specific heat capacity for water = 4200 J/kg.K

H = ṁcΔT = 5861.42

ΔT = 5861.42/(0.126 × 4200) = 11.08 K = 11.08°C

And in change in temperature terms,

10°C= 18°F

11.08°C = 11.08 × 18/10 = 20°F

ΔT = T₁ - T₂

20 = 180 - T₂

T₂ = 160°F

Q14) When you break a bar magnet in half, how many poles does each piece have?

Answers

Each piece of magnet has only two poles, one north and one south. So if you break a bar magnet into two halves, the piece initially consisting the north pole at the edge automatically creates the south pole at the break point and the part consisting south pole creates North pole at the edge. So each piece has 2 poles.

A magnet is an item or substance that generates a magnetic field. The broken pieces of the magnet will have 4 poles.

What are magnets?

A magnet is an item or substance that generates a magnetic field. This magnetic field is invisible, but it is responsible for a magnet's most remarkable property: a force that attracts or repels other ferromagnetic elements such as iron, steel, nickel, cobalt, and others.

When a magnet is broken into two pieces, it produces two complete magnets, each with its own north and south poles and the same orientation as the original.

For example, if you break a 12-inch bar magnet with N on the left end and S on the right end midway between the two ends, you'll get two magnets with N on the left end and S on the right end, as seen in the illustration below.

Hence, the broken pieces of the magnet will have 4 poles.
