Hello. You did not enter the data to which this question refers, which makes it impossible for it to have an exact answer. However, I will try to help you in the best possible way.

The forces that hold the elements together are called intermolecular forces. They are formed by covalent bonds between the molecules and can be called: dipole-induced (occurs between nonpolar molecules that have a negative pole and a positive pole) and dipole-dipole (occurs between polar moileculas, except when hydrogen is present).

Answer:

E=hf

Were, h = Planck constant 6.67*10^11

E=3.8*10^24 * 6.67*10^11= 2.508*q0^36j

Answer:

Explanation:

b. FALSE

If the velocity of particle is high then they will collide with each other with a greater force because their momentum will be high

force is a push or pull on a body .

Momentum is the product of mass and velocity,

More the velocity, higher will be the momentum.

since force is  directly proportional to rate of change of momentum

F = Δp/Δt

so on when bodies having higher velocities collide their rate of change of momentum is higher hence more will be the force

Explanation:

Answer:

Speed is solved with time and distance but has no direction

Average velocity is solved with Δx/Δt and has a direction

Explanation:

The clowns need to leave the diving boards with enough horizontal velocity such that each travels 15 m (half the width of the pool) in the same time that they fall (vertically) the 10-m from the top of the diving board.

We'll assume no force acts on the clowns horizontally to slow them down while they are in flight. And we'll assume that only gravity acts on the clowns vertically.

We can treat the horizontal and vertical components separately. This will help simplify the problem.

Let's start with the vertical displacement. Let's say the clown is dropped from a height of 10-m. How long would it take them to fall that distance?

Using our equations of motion (with constant, linear acceleration), we can solve for this time. [tex]d = vt + \frac{1}{2} at^2[/tex]

Where d is the distance travelled, v is the initial velocity, a is acceleration, and t is time.

If the clown is dropped, they have an initial velocity of 0 (zero). We assumed only gravity acts on the clown, so acceleration equals the gravitational acceleration on earth. [tex]a = 9.8m/s^2[/tex]

The distance the clown travels is 10-m from the diving board to the surface of the water.

Let's solve. [tex]10 = 0*t + \frac{1}{2} (9.8) t^2 \rightarrow 20/9.8 = t^2 \rightarrow t = \sqrt{20/9.8}[/tex]

Now that we know time, we can calculate how fast the clown needs to be running when they leap from the diving board to cover a distance of 15-m (Remember, half the width of the pool.)

Using our equations of motion, we know that [tex]d = vt + 0.5at^2[/tex]

We assumed no forces act horizontally on the clown, therefore a = 0. We just need to solve for v. Substituting in the time we just solved for, we get something like this. [tex]15 = v \sqrt{20/9.8}[/tex]

I'll leave it to you to solve this equation.

Answer:

A ball when from moving to stoping

Explanation:

Kinetic = energy of motion

Potential = energy stored

When you roll a ball on the ground, it gains kinetic energy, but then the ball starts to slow down until it stops and it remains at rest which means it's at potential energy. It went from moving (kinetic) to stoping (potential)

Hooke's law is a law of physics that states that the force needed to extend or compress a spring by some distance scales linearly with respect to that distance—that is, Fₛ = kx, where k is a constant factor characteristic of the spring, and x is small compared to the total possible deformation of the spring.

A person’s blood type depends on the type of protein marker, called an  Antigen, found on the cell membranes of the red blood cell.

A molecule known as an antigen is one that triggers the formation of an antibody and the immune system's response.

Large protein molecules known as antigens are found on the surface of pathogens like bacteria, fungi, viruses, and other foreign substances. When these dangerous substances enter the body, the body's immune system reacts by producing antibodies.

The ABO system distinguishes 4 major blood types:

B) Feather. If you want to be able to blow a bowling ball in a vaccum cleaner, it's almost impossible since it's very heavy. If it's a feather, it would be easier as it's light and the air inside it is able to force it down.

The correct answer is decreases in the troposphere and increases in the stratosphere.

For this reason, the density of gases decreases as the distance from Earth's surface increases. Put another way, air pressure (i.e., density) decreases as altitude increases.

The temperature of a place decreases with increasing altitude from the earth's surface.

Answer:

Explanation:

Given

Cyclist 1:

[tex]Distance = 40km[/tex]

[tex]Time = 2hr[/tex]

[tex]Direction = East[/tex]

Cyclist 2:

[tex]Distance = 10km[/tex]

[tex]Time = 0.5hr[/tex]

[tex]Direction = West[/tex]

The question requires options. Since none is given,  I'll answer on a general term.

First, calculate the speed of both cyclists

[tex]Speed = \frac{Distance}{Time}[/tex]

Cyclist 1:

[tex]Distance = 40km[/tex]

[tex]Time = 2hr[/tex]

[tex]Speed = \frac{40km}{2hr}[/tex]

[tex]Speed = 20km/hr[/tex]

Cyclist 2:

[tex]Distance = 10km[/tex]

[tex]Time = 0.5hr[/tex]

[tex]Speed = \frac{10km}{0.5hr}[/tex]

[tex]Speed = 20km/hr[/tex]

The following can be deduced from above:
