Answer:

a. Scalar quantity

b. Scalar quantity

c. Scalar quantity

Explanation:

Generally, all physical quantities can be categorized into vector or scalar. Vector quantities can be described by both magnitude and direction, while scalar quantities can be described only by magnitude.

a. 20 degrees Celsius is a measure of a definite value of temperature, thus it is a scalar quantity. As temperature has no direction.

b. 256 byte is the storage capacity of an electronic device. It is a scalar quantity since it is described only by magnitude and no direction.

c. 4000 Calories is an amount of energy in a given substance. Thus, it is a scalar quantity.

Answer:

In the case of the table and the book, the gravitational attraction is absolutely negligible, since they are both so tiny. The force that the table experiences because of the book is what is being called normal force. The table then exerts an equal and opposite force.

Explanation:

Explanation:

The law of motion states that for every action there is an equal yet opposite reaction. so that mean that the book is being acted on by another force which would be the table. It does not move because the table is acting on it with 8n of upward force creating an equilibrium keeping the book at rest.

Answer:

a)    P = 60.26 diopter ,  b)   h´ = -0.4 mm ,  c)   h´ = -0.16 mm

Explanation:

a)  For this exercise we use the equation for thin lenses

               1 / f = 1 / p + 1 / q

where f is the focal length, p the distance to the object and q the distance to the image

in this case q is the distance from the lens to the retina q = 2.00 cm

the distance p is the distance from the object to the lens p = 9.75 cm

               1 / f = 1 / 9.75 + 1/2

               1 / f = 0.6026 cm⁻¹

power is the inverse of the focal length in meters

              P = 1 / f [m]

              P = 0.6026 102

              P = 60.26 diopter

b)  the size of the image

             m = - p / q

             m = - 2 / 9.75

             m = -0.2 X

if we assume that the object is right

            m = h´ / h

            h´ = m h

            h´ = -0.2 2

            h´ = -0.4 mm

if the height of the object h is straight the image and inverted

c) if the object were at p = 25.0 cm

           m = - 2/25

           m = -0.08

             h´ = -0.08 2

             h´ = -0.16 mm

the image would be much smaller

Answer:

3622.5 K

Explanation:

The radiation of red giant star is 800nm.

We need to find the surface temperature of the star. Let it is T.

Using Wein's displacement law to find it as follows :

[tex]\lambda=\dfrac{C}{T}[/tex]

C is constant an T is temperature

[tex]T=\dfrac{C}{\lambda}\\\\T=\dfrac{2.898\times 10^{-3}}{800\times 10^{-9}}\\\\ T=3622.5\ K[/tex]

So, the surface temperature of the star is 3622.5 K.

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. the greater the mass, the greater the gravitational pull. gravitational pull decreases with an increase in the distance between two objects. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

I don't think your appendix can explode because you ate too much honestly. It's not even possible to eat so much that your appendix explodes, and if you're feeling any pain it definitely isn't because your appendix is about to explode, believe me. Also you could just type it into the internet, that'd be a much faster solution.

Money is transferred from your account to creditors' accounts

Explanation:

When performing online activities that require payments of bills on a computer. The very moment you decided to pay your bills using a computer, your money will be transferred immediately from your account to creditors' accounts. This will imply that the transaction is successful and you have paid your bills.

Hence, in this case, the correct answer is "Money is transferred from your account to creditors' accounts."

The rests of a transverse wave are like the compression of the longitudinal waves.

In terms of physics, a transverse wave refers to the wave where  oscillations should be perpendicular to the direction of the wave's in advance. This is in contrast to a longitudinal wave that travels in the direction of its oscillations.

Therefore, we can conclude that The rests of a transverse wave are like the compression of the longitudinal waves.

Answer:

The magnitude of the magnetic force on the proton is 9.532 x 10⁻¹⁷ N

Explanation:

Given;

speed of proton, v = 850 m/s

magnitude of magnetic field, B = 0.7 T

Charge of proton, q = 1.602 x 10⁻¹⁹ C

The magnitude of the magnetic force on the proton;

F = qvB

F = ( 1.602 x 10⁻¹⁹)(850)(0.7)

F = 9.532 x 10⁻¹⁷ N.

Therefore, the magnitude of the magnetic force on the proton is 9.532 x 10⁻¹⁷ N

Answer:

space = 66.24 [m]

Explanation:

To solve this problem we must remember that the average speed is defined as the relationship between a space traveled over a certain time.

[tex]Av = \frac{space}{time}[/tex]

space [m]

Av = average velocity = 3.6 [m/s]

time = 18.4 [s]

Answer:

d = 2.3 x 10⁻⁴ m = 0.23 mm

Explanation:

In a Young's Double Slit experiment the distance between two consecutive minima is given as:

Δx = λL/d

for, the distance between the 1st and 3rd minima it will become:

2Δx = 2λL/d

where,

2Δx = distance between 1dt and 4rd minima = 3 mm = 0.003 m

λ = wavelength = 690 nm = 6.9 x 10⁻⁷ m

L = Distance of Screen = 50 cm = 0.5 m

d = width of slit = ?

Therefore,

0.003 m = 2(6.9 x 10⁻⁷ m)(0.5 m)/d

d = 6.9 x 10⁻⁷ m/0.003 m

d = 2.3 x 10⁻⁴ m = 0.23 mm

Answer:

The average power of the engine of the sports car is 56.32 kW

Explanation:

Given;

mass of the sports car, m = 1100 kg

initial velocity of the sports car, u = 0 m/s

final velocity of the sports car, v = 32 m/s

time of motion, t = 10 s

The kinetic energy of the car is given by;

K.E = ¹/₂m(v² - u²)

K.E = ¹/₂mv²

K.E = ¹/₂ x 1100 x 32²

K.E = 563200 J

The average power of the engine of the sports car is given by;

Pavg = Energy / time

Pavg = 563200 / 10

Pavg = 56320 W

Pavg = 56.32 kW

Therefore, the average power of the engine of the sports car is 56.32 kW

Answer:

The phenomenon is known as refraction. The correct option is B

Explanation:

Refraction is defined as the property of a change in the direction of light, when it passed from one medium to another. In the process of refraction, the direction to which the rsy of light follows changes as well as the velocity, but the frequency remains the same along the line of propagation.

The extent of propagation is determined by the nature of the medium allowing the propagation.If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass. However, much of the light will pass through the glass, because glass is transparent. This effect also o view with mediums such as water.

The reason why the light rays bends away from its normal direction is that light slows down when it passes from the less dense air into the denser glass or water.

Other properties of light includes:

--> light travels in a straight line

--> light can be reflected

--> light can be diffracted

--> light can be polarized
