Explanation: i said so andddd when i put this it said it was right hehe

The speed of the mass at position A and B is approximately 0 m/s and 7.67 m/s respectively.

To determine the speed of the mass at positions A and B, use the principles of conservation of energy.

At position A, the ball is at its highest point on the slope. No kinetic energy. Equate the potential energy at A to the kinetic energy at position B, where the ball has traveled a distance of 4.00 m downhill.

Using the conservation of energy equation:

Potential Energy at A = Kinetic Energy at B

mghA = (1/2)mvB²

Where:

m = mass of the ball (which cancels out in this equation)

g = acceleration due to gravity (9.8 m/s²)

hA = height at position A (3.00 m)

vB = speed at position B (to be determined)

Substituting the given values:

(9.8 m/s²) × (3.00 m) = (1/2) × vB²

29.4 = 0.5 × vB²

Dividing both sides by 0.5:

58.8 = vB²

Taking the square root of both sides:

vB ≈ 7.67 m/s

Therefore, the speed of the mass at position B is approximately 7.67 m/s.

At position A, the speed of the mass is 0 m/s since it has reached its highest point and momentarily comes to a stop before descending.

Q = 5303.95 kJ

EXPLANATION

We are looking for the energy needed to evaporate 2.35kg of water. Since the water is already at evaporation temperature, which is 100°C, we just have to use latent heat. Also, we just want the steam to be at 100°C, so we don't need to find the energy to change its temperature.

The energy needed to evaporate water of mass m is:

L is the latent heat of the material, in this case water. There are two latent heats, one of fusion and one of vaporization. We have to use the second one, which for water is approximately 2257 kJ/kg

Therefore, to boil 2.35 kg of water at 100°C to steam at 100°C we need:

Milliliters (ml) or cubic millimetres are the most suitable units for calculating a raindrop's volume (mm3).

Raindrops are quite tiny and usually have volumes between 0.1 and 0.5 millilitres. Small, precise volume measures like millilitres or cubic millimetres are ideal for measuring these volumes.

A raindrop's volume can change depending on its size and form, as well as external conditions like air pressure and temperature.

For measuring the volume of a single raindrop, units of volume such as litres or cubic metres are too vast and would not offer sufficient precision. Thus, the units that are best suited for measuring the volume of a raindrop are millilitres or cubic millimetres.

It is true that Newton's first law states that an object in motion will stay in motion unless acted upon by external force.

Another name for Newton's first law of motion is the law of inertia. According to this law, unless an external force acts upon an object, it will continue to be at rest or move at a constant speed.

An object's motion will not change unless something outside of the object causes it to change. This law helps us explain why objects tend to keep doing what they are already doing unless something happens to stop them or change their motion.

We cannot determine the change in resistance due to a change in temperature.

The temperature coefficient of resistivity (alpha) of a substance measures how its resistivity changes with temperature. The formula for finding the change in resistance of a conductor due to a change in temperature is:ATR=alpha * R * ATT

where R is the original resistance of the conductor, ATT is the change in temperature, and ATR is the change in resistance. So, ATR = alpha * R * ATT

For a conductor made of a material whose temperature coefficient of resistivity is 3.810° rap, the change in resistance when the temperature rises by ATTT degrees Celsius is given by:ATR = (3.810 × 10⁻³⁰/°C) × R × ATTTwhere R is the original resistance of the conductor.The problem does not give us the original resistance of the conductor.

Mass = 10 g

Change in temperature = 140°C

Quantity of heat = 2000 J

To find the specific heat capacity;

Heat capacity is given by the formula;

\( Q = mcdt\)

Where;

Making c the subject of formula, we have;

\( c = \frac {Q}{mdt} \)

Substituting into the equation, we have;

Specific heat capacity, = 1.43 J/g°C

They all have the same average kinetic energy, which is directly proportional to their temperature. This is a consequence of the kinetic theory of gases, which states that the average kinetic energy of gas molecules is directly proportional to the temperature of the gas.

The masses and average velocities of the gases, on the other hand, can vary widely depending on the type of gas. Heavier gases, such as carbon dioxide, will have lower average velocities compared to lighter gases, such as helium, at the same temperature. However, despite these differences, all gases in the mixture will have the same average kinetic energy as long as they are at the same temperature. This is an important principle in thermodynamics, which helps us understand the behaviour of gases under different conditions.

The inverse square law is a principle in physics that states that the intensity or strength of a particular phenomenon (such as light, sound, or gravity) decreases in proportion to the square of the distance from the source of the phenomenon. The formula for the inverse square law is I = P/(4pir^2) where I is the intensity of the phenomenon, P is the power of the source, r is the distance from the source, and pi is a mathematical constant.

To understand the inverse square law, consider a lightbulb as an example. If you were to measure the intensity of the light coming from the lightbulb at a distance of 1 meter, and then measure it again at a distance of 2 meters, you would find that the intensity at the second point is one-fourth of the intensity at the first point. This is because the light is spreading out over a larger area (the surface of a sphere with a radius of 2 meters) as it travels away from the source, and the intensity is distributed over that larger area.

The inverse square law applies to any phenomenon that spreads out in a spherical shape as it travels away from its source. This includes light, sound, and gravity. For example, in the case of gravity, the force of attraction between two objects decreases in proportion to the square of the distance between them. So if you were to double the distance between two objects, the force of attraction between them would be one-fourth of what it was before.

It's important to note that the inverse square law only applies in three-dimensional space. In two-dimensional space, the intensity decreases proportionally to the distance squared.

In summary, the inverse square law states that the intensity of a phenomenon decreases as the distance from its source increases, in proportion to the square of the distance. This principle is important in many areas of physics and engineering, from understanding the behavior of light and sound to designing systems that use or interact with these phenomena.

B. Current increases because it is directly proportional to voltage

Explanation:

Ohms law is used to show the relationship between the current, voltage and resistance of a substance. The Ohms law equation is as follows:

V = IR

Where;

V = voltage (volts)

I = current (amperes)

R = resistance (ohms)

Based on these equation, it is evident that the current (I) is directly proportional to the voltage (V), hence, as the voltage increases, the current also increases. According to this question, when the voltage is tripled (increased), the current also increases because it is directly proportional to voltage.

Answer:

1)10 m/s

2) 20 m/s

3) 2 s

4) 500 m

5)1000 km/h

Average speed = distance travelled / time.

( note: distance must be in (m) and time in sec, if not then you convert ).

1) average speed = 20/2 = 10mls.

2) average speed = 100/5 = 20 m/s.

3) since we aren't given (time) let's call it x

so we replace the unknown time with x..

average speed = 2/x = 1

then cross multiply

you get x (the unknown time) as 2s {seconds}.

(to check if it's correct just add the time we got back into the equation and see if you would get a erage speed as 1m/s).

4) do the same, replace distance as x or any letter you want )

average speed = x/ 10 = 50

cross multiply

you get x = 500m {meters}

5) (we need to convert km to meters and time to secs because that's what we are working with).

200km = 200,000 m { to convert to meters you multiply the given by 1000, 1km = 1000m).

for 2h, we know that:

60 seconds makes 1 minute

60 minutes makes an hour.

so we multiply 60 by 60 we get 3600mins then we multiply it by 2 to get 7200 secs

so now

Average speed = 200,000/7200 = 27.77 m/s.
