Explanation:

i took the test

A collection area gains water as runoff from precipitation or precipitation falling into the collection area.

A collection area is an area set aside for the purpose of collecting water. This water could come into the collection area as precipitation or as surface run off.

Hence, a collection area could gain water via;

Answer:

the cost of running the bulbs is 11.25p

Explanation:

Given;

cost of running 1 kwh = 10 p

power of filament bulb, P = 60 W

power of the CFL bulb, P = 15 W

time of power consumption, t = 15 hours

Total Energy consumed;

E = (60W + 15W) x 15 hours

E = (75)(15)

E = 1125 Wh

E = 1.125 kWh

Cost of 1.125 kWh  =   1.125 x 10p

                               = 11.25p

Therefore, the cost of running the bulbs is 11.25p

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:

Final velocity, V = 35.5m/s

Explanation:

Given the following data;

Initial velocity = 28m/s

Acceleration = 2.5m/s²

Time = 3 seconds

To find the final velocity, we would use the first equation of motion

V = U + at

Where;

V is the final velocity measured in m/s.

U is the initial velocity measured in m/s.

a is the acceleration measured in m/s².

t is the time measured in seconds.

Substituting into the equation, we have;

V = 28 + 2.5*3

V = 28 + 7.5

Final velocity, V = 35.5m/s

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.

3. fish interact with there no living things like how one would hide in the grass or something like that.

4. decorations (like a cave or fake house, tho the aquarium its self is a home)

5.they would die, and rot.

Explanation:

rocks are nonliving

fish are living things and so are plants

fish can hide in the plants

the fish can "live" in the decorations, but the aquarium itself is its home.

if something reaches the end of its life span it dies.

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

Answer:

Initial velocity, U = 28.73m/s

Explanation:

Given the following data;

Final velocity, V = 35m/s

Acceleration, a = 5m/s²

Distance, S = 40m

To find the initial velocity (U), we would use the third equation of motion.

V² = U² + 2aS

Where;

V represents the final velocity measured in meter per seconds.

U represents the initial velocity measured in meter per seconds.

a represents acceleration measured in meters per seconds square.

S represents the displacement measured in meters.

Substituting into the equation, we have;

35² = U + 2*5*40

1225 = U² + 400

U² = 1225 - 400

U² = 825

Taking the square root of both sides, we have;

Initial velocity, U = 28.73m/s

Any material that has ferromagnetic property

Explanation:

Materials such as  iron, nickel or cobalt are ferromagnetic element as they behave as small magnets in the presence of moving electric charge or static magnetic field.

When an external magnetic field is applied these ferromagnetic material align in a way that they contribute to produce a stronger magnetic field in the material and remain aligned even after removal of the external magnetic field.
