☆<《HOPE IT WILL HELP YOU 》>☆

Explanation:

The formula for finding TRIANGLE is Half + Base × Hight

If 60 Joules of energy are applied to the bricks, so   the lever’s efficiency is 60%.

Efficiency is a measure of how well a machine or system transforms input energy into useful output energy. It is a ratio of output energy to input energy. In this case, the team of students builds a lever as a science project. They expend 100 Joules of energy to lift some bricks with the lever. If 60 Joules of energy are applied to the bricks, what is the lever’s efficiency? In this case, we have;

Total input energy, I = 100 J

Total output energy, O = 60 JEfficiency, η = Output energy/Input energyη = O/II = O/ηη = O/I = 60/100 = 0.6

or 60%Therefore, the efficiency of the lever is 60%.

This implies that the lever converts 60% of the input energy to useful output energy. That is, it requires 100 J of input energy to lift the bricks, but only 60 J of energy is applied to the bricks. The remaining 40 J is lost due to friction, air resistance, or other forms of energy dissipation.

Answer:

tsunamis are waves created from A tsunami is a catastrophic ocean wave that is usually caused by a submarine earthquake, an underwater or coastal landslide, or the eruption of a volcano. Tsunamis can also result from the impact of a meteor or comet in a body of water. when one of these events happen all the water near the shore of it will drawn back toward where the tsunamis will form, the waves emerge into one and a tsunamis born, unlike normal waves the tsunami move very fast and they can get very big and more devastating.

a wave is caused by wind, The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds cause larger waves and a lot of them are not as dangerous as tsunamis, however that's not always the case, since waves like  Rogue waves are big and powerful enough to sink ships, ocean liners, and even oil platforms, same with tsunamis.

Answer:

b

Explanation:

The relative distance can calculate by dividing the time travelled by the speed difference between points A and B. Considering that B is going more quickly than A, we substract A's speed from B's speed.

Relative Speed = Speed of B - Speed of A

Relative Speed = 6 km/h - 5 km/h

Relative Speed = 1 km/h

Now, we can calculate the relative distance traveled by B after 2 hours:

Relative Distance = Relative Speed * Time

Relative Distance = 1 km/h * 2 hours

Relative Distance = 2 km

Therefore, B will be 2 kilometers away from A after 2 hours of walking in the same direction.

The factor that does NOT influence wind speed and direction is radiation. Hence, the correct option is (e). The factor that does NOT influence wind speed and direction is radiation.

The other four factors that influence wind speed and direction are friction, pressure gradient, Coriolis effect, and high-to-low pressure difference.

Pressure gradients usually develop due to unequal heating of the atmosphere. Hence, the correct option is (c). Pressure gradients usually develop due to unequal heating of the atmosphere.

Pressure gradients occur due to differences in air temperature, which cause pressure differences. Areas with warmer air will have lower pressure while those with cooler air will have higher pressure.

The wind blows from the sea to land because warm land has low pressure and cooler sea has higher pressure is the best description of how a sea breeze works. Hence, the correct option is (a).

A sea breeze is a type of local wind that blows from the sea towards the land. This occurs because during the day, the land heats up faster than the sea, causing the air above it to rise.

This creates a low-pressure area above the land. At the same time, the sea remains cooler, and the air above it is denser, creating a high-pressure area. The air flows from the high-pressure area (the sea) to the low-pressure area (the land), creating a sea breeze.

This breeze usually occurs in the afternoon when the temperature difference between the land and sea is greatest. It helps to cool down the land and bring moisture from the sea to the land.

The sea breeze is a result of differences in air temperature and pressure between the land and sea, with the wind flowing from high to low pressure, bringing moisture to the land and cooling it down.

Winds are bent to the right from the flow driven by the pressure gradient in the northern hemisphere, based on the Coriolis effect. Hence, the correct option is .

Based on the Coriolis effect, winds are bent to the right from the flow driven by the pressure gradient in the northern hemisphere. The Coriolis effect occurs due to the Earth's rotation, causing moving objects such as wind to deflect to the right in the northern hemisphere and to the left in the southern hemisphere.

The frictional force works opposite the motion of the wind, slowing it down. Hence, the correct option is (e). The frictional force works opposite the motion of the wind, slowing it down.

Friction occurs when the wind blows over the surface of the Earth, causing drag and slowing down the wind. The frictional force works opposite to the direction of the wind, with the greatest friction near the surface and decreases with height.

The radius of the bowling ball is approximately 7.65 inches.

We can use the formula for the surface area of a sphere to find the radius of the bowling ball:

Surface area of a sphere = 4πr²

where r is the radius of the sphere.

In this problem, we are given the surface area of a bowling ball, which is 232 square inches. We can use this information and the formula for surface area of a sphere to solve for the radius of the ball. Plugging this value into the formula, we get:

232 = 4πr²

Dividing both sides by 4π, we get:

r² = 58.5

Taking the square root of both sides, we get:

Explanation:

There is only two needed factors in play here; the mass and acceleration

According to Newton's 2nd Law: F = m*a

Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2

the critical angle for red light in diamond is 24.51°

critical angle for violet light in diamond is 24.01°.

given:

wavelength of red light λr =660nm

wavelength of violet light λv =410nm

refractive index for air=1

as the refractive index of red and violet colour in diamond is

Refractive index of red color nr= 2.407

Refractive index of violet color nv= 2.451

as it is mentioned that angle is critical angle,thus θr =90°

so,from Snell's law

n1sinθc=n2 sin 90°

Here,

n1 is the refractive index for incident medium

n2 is the refractive index for refractive medium

θc is the critical angle after which light starts reflecting internally

The critical angle for red light is here,n1=2.407, n2=1

n1sinθc=n2 sin 90°

2.407×sin θc=1×1

sin θc =(1/2.407)

θc=sin-1 0.415

θc=24.51°

Thus,the critical angle for red light in diamond is 24.51°

The critical angle for violet light is,

here,n1=2.451,n2=1

n1sinθc=n2 sin 90°

2.407×sin θc=1×1

sin θc= (1/2.451)

θc=sin-1 0.407

=24.01°

Thus,the critical angle for violet light in diamond is 24.01°.

If an inflated beach ball seems only partially inflated in the morning, then it will appear more inflated after being left out in a hot, sunny spot for several hours. This is because heat causes air molecules to move faster and spread apart, which leads to an increase in air pressure inside the ball.

As a result, the beach ball will become more fully inflated as the air pressure inside it increases due to the exposure to the hot, sunny spot.

Another factor that could contribute to the beach ball appearing more inflated after being left out in the hot, sunny spot for several hours is the expansion of the rubber material of the beach ball.

As rubber material absorbs heat, its molecules vibrate more rapidly, which causes the rubber to expand. This expansion can cause the beach ball to appear more inflated than it did in the morning.
