A golfer hits a golf ball upwards at an angle. We can ignore air resistance on the ball.
Which diagram best describes the velocity vectors and trajectory of the golf ball's motion?

When an earthquake occurs, rocks at a fault line slip or break, and two sections of Earth's crust physically move relative to one another. That movement releases energy, and two types of seismic waves radiate outward from the earthquake through Earth's interior and along its surface.

WHEREAS

Ocean waves are created by energy passing through water, causing it to move in a circular motion. ... Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

Answer:

An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction.

Answer:

Velocity of the moving objects with respect to other moving or stationary object is called “relative velocity” and this motion is called “relative motion”.

Explanation:

For example, you are in a bus and it goes with the velocity of 50 m/s to the east, then a truck passes you with a velocity of 60m/s to the east.

Answer:

Radiant energy from the Sun is converted into electrical energy. Electrical energy is then converted into chemical energy. Chemical energy is then converted into electric energy for the motor. The motor converts electrical energy into mechanical energy and makes the car move.

Sun makes radiant energy > converted to electrical energy through solar panels > converted to chemical energy which is then stored in a battery for the motor > converted into mechanical energy to make the car move

The energy transformations that can be seen in solar-powered electric cars :

Solar energy >  electrical energy > chemical energy  > mechanical energy.

A solar electric car is one that is primarily or entirely powered by solar energy. Solar panels typically feature photovoltaic (PV) cells that convert solar energy directly into electric energy. The phrase "solar vehicle" typically implies that all or some of a vehicle's propulsion is powered by solar energy. Communications, controls, and other auxiliary operations might all be powered by solar energy.

In solar electric car, solar energy converted into electrical energy by  photovoltaic (PV) cells. This energy is stored in battery in the form of chemical energy. When the car moves, this chemical energy transforms into mechanical energy.

Answer:

its b

Explanation:

b

Answer:

A

Explanation:

The antireflective coating applied to the protective glass on a solar cell maximize the energy absorbed by the solar cell as it helps the glass transmit the energy. The correct option is A.

The antireflective coating added to the protective glass of a solar cell is intended to reduce light reflection from the glass's surface.

More light may flow through the glass and reach the solar cell underneath it by decreasing reflections. This permits the solar cell to absorb more energy from the sun, increasing its efficiency in converting light into electricity.

The antireflective coating guarantees that a larger proportion of incident light is passed through the glass by decreasing reflection, allowing the solar cell to gather and use more energy.

Thus, the correct option is A.

Answer:

67.5 N

Explanation:

From the question given above, the following data were obtained:

Charge 1 (q₁) = 3.0×10¯⁶ C

Charge 2 (q₂) = 2.5×10¯⁷ C

Distance apart (r) = 1 cm

Force (F) =?

Next, we shall convert 1 cm to m. This can be obtained as follow:

100 cm = 1 m

Therefore,

1 cm = 1 cm × 1 m / 100 cm

1 cm = 0.01 m

Thus, 1 cm is equivalent 0.01 m.

Finally, we shall determine the electrical force between the two points charges as follow:

Charge 1 (q₁) = 3.0×10¯⁶ C

Charge 2 (q₂) = 2.5×10¯⁷ C

Distance apart (r) = 0.01 m

Electrical constant (K) = 9×10⁹ Nm²C¯²

Force (F) =?

F = Kq₁q₂ / r²

F = 9×10⁹ × 3.0×10¯⁶ × 2.5×10¯⁷ / (0.01)²

F = 0.00675 / 0.0001

F = 67.5 N

Therefore, the electrical force between the two points charges is 67.5 N

Answer:

15N South

Explanation:

It is 15N South because the two 15N cancel out each other and then you subtract 5N from the 20N and then you get left with 15N. and the 20N is bigger and it is going South.So the answer is 25N south.

Answer:

the answer would be 15N south

Given parameters:

Frequency  = 500Hz

Unknown:

a. Period of rotation

b. Time required to complete 7 rotation

Solution:

The period of rotation is the time taken to complete a turn.

      P = [tex]\frac{t}{n}[/tex]

P is the period

t is the time

n is the number of turns

  Period is the inverse of frequency;

        P = [tex]\frac{1}{500}[/tex]   = 0.002s

b.

Time required to complete 7 rotation;

            P  = [tex]\frac{t}{n}[/tex]  

           t  = P x n

t is the time

P is the period

n is the number of rotations

          t  = 0.002 x 7  = 0.014s

Answer:

The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second

Explanation:

Horizontal Launch

When an object is thrown horizontally with a speed v from a height h, it describes a curved path ruled exclusively by gravity until it eventually hits the ground.

To calculate the vertical distance (y) traveled by the object in terms of the time (t) we use:

[tex]\displaystyle y=\frac{g.t^2}{2}[/tex]

The fastball is thrown horizontally. The distance the ball falls in t=1/4 seconds = 0.25 seconds, is:

[tex]\displaystyle y_1=\frac{9.8*0.25^2}{2}[/tex]

[tex]\displaystyle y_1=0.30625\ m[/tex]

The distance the ball falls in t=1/2 seconds = 0.5 seconds is:

[tex]\displaystyle y_2=\frac{9.8*0.5^2}{2}[/tex]

[tex]\displaystyle y_2=1.225\ m[/tex]

The distance it falls in the second 1/4 second is:

[tex]y_2-y_1=1.225\ m-0.30625\ m[/tex]

[tex]y_2-y_1=0.91875\ m[/tex]

The ball falls 0.3 m in the first 1/4 seconds, and it falls 0.92 m in the second 1/4 second

hello your question is incomplete below is the complete question

Sheila lives in the seashore community of Beachview. At 6:00 a.m. one morning, she noticed that the local ocean water was at high tide. At approximately noon that same day, she noticed the water was at low tide.

Which of the following describes what caused the change in tides between 6:00 a.m. and noon that day

options :  

A)The Earth revolved approximately 90° around the Sun, and the gravitational attraction between the Moon and Sun increased.

B)The Earth completed one full rotation (360°), and the gravitational attraction between the Moon and the Beachview area increased.

C)The Earth completed one full revolution around the Sun (360°), and the gravitational attraction between the Moon and Sun decreased.

D)The Earth rotated approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.

answer :  

The Earth rotated approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.  ( D )

Explanation:

The movement of the Earth in the Galaxy occurs in two ways

namely: Rotation and Revolution and each movement comes has an effect on the earth, also each movement has a time frame as well.

The complete rotation of the earth about its axis takes about 24 hours and this rotation brings about Night and day and it also causes the rise and fall of tides. while the Revolution of the earth round brings about different seasons and it takes about 365 days for a complete revolution of the earth round the sun.

hence the the change in tides between 6:00 a.m. and noon that day is caused by The Earth rotating approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.
