Answer:

A change in pressure

Explanation:

This is because, the deeper you dive, the height of water above you creates a pressure on you. So, as the depth increases, the height of water increases, thus its weight on you, thus its pressure on you also.

Also, as you gain altitude as you climb a mountain, the height of air above you decreases. This thereby decreases the weight of air above you thus, decreasing the pressure of air on you.

So, in both cases, there is a change in pressure as height or depth changes. An increase in height results in decreased pressure and an increases in depth results in increased pressure.

Answer:

Oxygen is an element that can be a solid, liquid or gas depending on its temperature and pressure. In the atmosphere it is found as a gas, more specifically, a diatomic gas. This means that two oxygen atoms are connected together in a covalent double bond.

B: Solids

Explanation:

I have notes from EDG and I looked it up on the internet

I hope this helps

In the solids, convection can not occur. Convection can only be done in the fluids.

Under the effect of gravity, hotter, less dense material rises while colder, denser stuff sinks, resulting in heat transfer"Convection is the ultimate mode of energy transmission to the surface"

There are three modes of the heat transfer;

1. Conduction

2. Convection

3. Radiation

Convection occurs in the fluid which is liquid and gases. Convection never occurs in the solid.

Hence option B is correct.

Answer:

Angle - 120 degrees, 2.093 radians and 0.33 revolution

Explanation:

Minute hand is on the 12 and the hour hand is on the 4.

The angle formed between 4 and 12 is

[tex]\frac{4}{12} * 360 = 120[/tex] degrees

The angle formed between 4 and 12 in radian is

[tex]\frac{\pi }{180} * 120 = 2.093[/tex] radians

The angle formed between 4 and 12 in revolution is

[tex]\frac{2.093 }{2 \pi } \\= \frac{2.093 }{2* 3.14} \\= 0.33[/tex] revolution

Answer:

We now introduce two concepts useful in describing heat flow and temperature change. The heat capacity ( C ) of a body of matter is the quantity of heat ( q ) it absorbs or releases when it experiences a temperature change ( ΔT ) of 1 degree Celsius (or equivalently, 1 kelvin)

C=qΔT(12.3.1)

Heat capacity is determined by both the type and amount of substance that absorbs or releases heat. It is therefore an extensive property—its value is proportional to the amount of the substance.

For example, consider the heat capacities of two cast iron frying pans. The heat capacity of the large pan is five times greater than that of the small pan because, although both are made of the same material, the mass of the large pan is five times greater than the mass of the small pan. More mass means more atoms are present in the larger pan, so it takes more energy to make all of those atoms vibrate faster. The heat capacity of the small cast iron frying pan is found by observing that it takes 18,140 J of energy to raise the temperature of the pan by 50.0 °C

Answer:

The magnitude of magnetic force between the two parallel wires is 1.13 N.

Explanation:

Given;

length of each wire, l = 31 m

distance between the two parallel wires, r = 0.155 m

current on each wire, I = 168 A

The magnitude of magnetic force between the two parallel wires is calculated as;

[tex]F = \frac{\mu _oI_1I_2 L}{2\pi r} \\\\F = \frac{(4\pi \times 10^{-7}) \times (168)^2 \times (31)}{2\pi \times 0.155} \\\\F = 1.13 \ N[/tex]

Therefore, the magnitude of magnetic force between the two parallel wires is 1.13 N.

Explanation:

Answer:

C

Explanation:

Warm water and precipitation are transported from the equator to the poles by ocean currents, whereas cold water is returned to the tropics from the poles. Ocean currents control climate globally by balancing out the uneven distribution of solar radiation that reaches Earth's surface.

Short-distance currents can travel across entire ocean basins, while longer ones can even circle the earth. Ocean currents are vital in regulating the climate because they transport heat from the equator to the poles.

The distribution of air temperature is significantly influenced by ocean circulation. The warm Gulf Stream in the North Atlantic and the chilly Peru (Humboldt) Current in South America are two examples of ocean currents with a northward or southbound component that efficiently exchange heat between low and high latitudes.

Answer:

GPE = 388.08 Joules.

Explanation:

Given the following data;

Mass = 0.550kg

Speed = 335 m/s

Height = 72 meters

We know that acceleration due to gravity, g is equal to 9.8 m/s²

To find the gravitational potential energy;

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the formula, we have;

[tex] G.P.E = 0.550 * 9.8 * 72[/tex]

GPE = 388.08 Joules.

Answer:

*The same balloon put into the freezer would be smaller and shriveled.

* The volume decreases as the temperature decreases.

* using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2

V2= 1.54 liters which proves when temperature decreases , volume decreases as well.

Explanation:

The volume increases as the temperature increases, and volume decreases as the temperature decreases.

using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2

Change Celsius to kelvin by adding 273.

2 liters/ 315 K = V2/243 K

Cross multiply and then divide by 315 to find V2

2 liters x 243 K / 315 K = V2

The Kelvin cancels itself out.

486 liters /315=V2

V2= 1.54 liters.

This proves that when the temperature decreases , so does the volume.

Answer:

A, C

Explanation:

In order for a box to be moving at constant velocity, that means acceleration must be 0(as the speed isn't increasing). Thus, since F = ma, and a is 0, the net force must also be 0. The diagram must be completely balanced in every direction, which is why the two horizontal arrows must be equal values.

C is also true because gravity is a stronger force here than the applied force. We can calculate the force due to gravity with Fgravity = mg. Thus, we get the force as a result of gravity = 9.8*50, which is around 500N and much larger than the applied force of 200N.

Explanation:

Given that a student pulls down with a force of 40 N on a rope that winds around a pulley of radius 5 cm. find the torque?

Solution

Using the formula

Torque = Force × radius

I.e

Torque = F r

Where

F = 40N

r = 5 cm = 5/100 = 0.05m

Substitute all the parameters into the formula

Torque = 40 × 0.05

Torque = 2 N

Therefore, the torque on this scenario is 2 N

Answer: 2934.75 Joules

Explanation:

Potential energy can be defined as energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

P.E = mgh

Where P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per second square.

h represents the height measured in meters.

Given the following data;

Weight =645

Height = 4.55

P.E = mgh

But we know that weight = mg = 645N

Substituting into the equation, we have;

P.E = 645 • 4.55

P.E = 2934.75J

Potential energy, P.E = 2934.75 Joules.

Let's reduce the magnitudes to the SI system

           r = 0.5 cm (1m / 100cm) = 5 10⁻³ m

let's calculate

           F = [tex]9 \ 10^9 \frac{(2.5 \ 10^{-6})^2 }{(5 \ 10^{-3})^2}[/tex]

           F = 2.25 10³ N

b) In electricity, electric charges of the same sign repel and those of the opposite sign attract

In this exercise, the balls are equal and are rubbed with the same material, for which it acquires charges of the same type, consequently, as the charges are of the same type, they indicate that the negative force is REPULSIVE.
