a

Explanation:

a is the answer to that question, increasing air resistance surrounding air

Answer:

magnetically saturated

Explanation:

When all of the domains are aligned, the material is said to be magnetically saturated. When a material is magnetically saturated, no additional amount of external magnetization force will cause an increase in its internal level of magnetization.

Explanation:

1. Convex mirror is curved outward.

2. Convex mirror forms an image that is smaller than the object.

3. Concave mirror is used to focus light rays. That's why it is also known as a converging mirror.

4. Plane mirror has a flat surface. It forms the same size of the image as that of the object.

The reflective surface of a convex mirror, also known as a curved mirror, bulges toward the light source.

Thus, A curved mirror's surface can be convex, meaning it bulges outward, or concave, meaning it bulges inward. Since a convex mirror reflects light outward, it cannot be utilized to concentrate light.

Because the focus and center of curvature are fictitious positions inside the mirror and are therefore unreachable, convex mirrors or curved mirrors always produce a virtual image.

As a result, convex mirror images cannot be projected onto a screen. The picture is also smaller than the projected object, but it grows larger as it goes closer to the convex mirror.

Thus, The reflective surface of a convex mirror, also known as a curved mirror, bulges toward the light source.

Answer:

0.0025 kilograms

Explanation:

There are a 1000 grams in 1 kilogram, so that means that there are

0.0025 kilograms in 2.5 grams.

Answer:

Below

Explanation:

● 1 kg = 1000 g

Divide both sides by 1000

● 1/1000 kg = 1000/1000 g

● 0.001 kg = 1 g

Multiply both sides by 2.5

● 2.5 g = 0.001 × 2.5 kg

● 2.5 g = 2.5 × 10^(-3) kg

● 2.5 g = 0. 00 25 kg

Answer:

(C) Average Velocity = 25 m/s due North

Answer:

A -TRUE

Explanation:

The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration.

Answer:

centrifugal force and kinetic energy

Explanation:

Without centrifugal force and kinetic energy, a car would be unable to move.

A centrifugal force regulates the speed of the engine using spinning masses and causes radial movement when the engine changes speed.

The kinetic energy is the energy which an object possesses due to its motion and car also require kinetic energy to move.

Hence, the correct answer is centrifugal force and kinetic energy.

Answer:

False

Explanation:

They both posses constant acceleration

B - False

Answer:Scientific Investigations

Explanation:

Answer:

a) according to Faraday's law , b) creating a faster movement, placing more turns on coil

Explanation:

a) The voltage is induced in the coil by the relative movement between it and the magnet, therefore according to Faraday's law

           E = - d (B A) / dt

In this case, the magnet is involved, so the value of the magnetic field varies with time, since the number of lines that pass through the loop changes with movement.

This voltage creates a current that charges the battery

b) There are several ways to increase the voltage

* creating a faster movement, can be done by the user

* placing more turns on the coil, must be done by the manufacturer

Answer:

1000 J which agrees with answer a in your list of options

Explanation:

W = F * d

W = 200 N * 5 m = 1000 J

Answer:

It is proportional or directly related....

Answer:

196000 N

Explanation:

The following data were obtained from the question:

Height (h) = 10 m

Area (A) = 2 m²

Force (F) =.?

Next, we shall determine the pressure in the tank.

This can be obtained as follow:

P = dgh

Where

P is the pressure.

d is the density of the liquid.

g is acceleration due to gravity

h is the height.

Height (h) = 10 m

Density (d) of water = 1000 kg/m³

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

Pressure (P) =...?

P = dgh

P = 1000 × 9.8 × 10

P = 98000 N/m²

Therefore, the pressure acting on the tank is 98000 N/m²

Finally, we shall determine the force of gravity acting on the column of water as follow:

Area (A) = 2 m²

Pressure (P) = 98000 N/m²

Force (F) =.?

Pressure (P) = Force (F) /Area (A)

P = F /A

98000 = F/ 2

Cross multiply

F = 98000 × 2

F = 196000 N

Therefore, the force of gravity acting on the column of water is 196000 N

C deceive participants

Explanation:

It is ethical practice to come clean or tell the truth about being deceptive at the end of the study.  They need to be told that they were deceived.  

In order to stop experimental subjects from trying to confirm the scientist's hypothesis, psychologists sometimes deceive participants about the true purpose of the experiment. The correct option is C.

Psychologists can help people learn to cope with stressful situations, overcome addictions, manage chronic illnesses, and administer tests and assessments that can aid in the diagnosis of a condition or reveal more about a person's thoughts, feelings, and behaviors.

Psychotherapy can be aided by both psychologists and psychiatrists.

However, most psychiatrists treat patients primarily through medication, whereas psychologists primarily treat patients through talk and/or behavioral therapy.

People seek the help of a clinical psychologist to deal with mood-related issues such as depression, mania, anger, or anxiety.

Psychologists sometimes deceive participants about the true purpose of the experiment in order to prevent experimental subjects from attempting to confirm the scientist's hypothesis.

Thus, the correct option is C.

Answer:

600 mC

Explanation:

The charge of an electron is 1.6 x 10-19C so for a current with 10 mA, the charge going to screen in one second is 10 mC

so number of electrons, n = (10 x 10-3)/(1.6 x 10-19) = 6.25 x 1016  so in a minute the charge is 10 * 60 = 600 mC

Answer:

Total charge, q = It = 10 A x 60 s = 600 C

We know that, q = ne

So no. of electrons, n = q/e = 600 / (1.6×10-19) = 375x1019
