Answer:

R = 0.24 kilo-ohm

Explanation:

Given that,

Voltage, V = 12 volt

Current, I = 50 mA = 0.05 A

We need to find the resistance of the resistor. We can find it using Ohm's law. So,

V = IR

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{12}{0.05}\\\\R=240\ \Omega[/tex]

or

R = 0.24 kohm

So, the value of resistance is 0.24 kilo-ohm.

Explanation:

Answer:

mass equals 375 kg

Explanation:

f=ma

f=7500

a=20

m=f/a

m=7500/20

m=375

1500 kg  is the mass of the car​.

Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it.

Newton's second law is often stated as,

F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a).

According to the question,

Mass = 20m/s , Time = 4s , Force = 7500 N

a = Δv/Δt

a = 20m/s / 4s

a = 5 m/s²

If F = ma then,

7500 N =  m x 5 m/s²

m = [tex]\frac{7500 N }{ 5m/s^{2} }[/tex]

m = 1500 kg

Therefore,

1500 kg  is the mass of the car​.

Answer:

50N

Explanation:

Impulse = Force × Time

25 = Force × 0.5

Force = 25/0.5

= 50N

Answer: I believe it may be 18m/s I apologize if it isn't but have a great day :DDD

Answer:

25 cm³

Explanation:

In the conversion of units, we know that are one cubic centimeters (cm³) in a milliliter (mL) .

1 milliliter = 1 cubic centimeter

25 milliliters = 25 cubic centimeters

Therefore, a volume of 25 milliliters is the same as a volume of 25 cubic centimeters.

This ultimately implies that, the volume of an object in milliliters is equivalent to its volume in cubic centimeters.

Answer:

V = 360 kV

Explanation:

Given that,

Charge, q = -2µC

We need to find the electric potential difference of 5cm from a point charge.

We know that the formula for the electric potential is given by :

[tex]V=\dfrac{kq}{r}\\\\V=\dfrac{9\times 10^9\times 2\times 10^{-6}}{0.05}\\\\V=360000\ V[/tex]

or

[tex]V=360\ kV[/tex]

So, the electric potential difference is 360 kV.

Answer:

Distance covered by Anthony is 3 km. Don't know about displacement though.

Answer:

Position.

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.

Hence, a reference point allows you to determine the position an object.

Answer:

Water vapor

Explanation:

Water Vapor has the highest temperature, due to its being in a gas state, and gases usually have very high temperatures, for example steam when you boil pasta.

Hope this helps you! Have a nice day!

Answer:

Explanation:

Frictional force = 7000 N

mass of car = 1300 kg . Initially car was moving uniformly so no force acting on car at that time . After frictional force acts , it creates deceleration or negative acceleration .

acceleration = force / mass

= - 7000 / 1300

= - 5.38 m / s²

Uranium is an element. Uranium is a pure substance kind of matter. Thus, the correct option is A.

A pure substance is a single type of matter which cannot be separated or divided into other smaller kinds of matter through any kind of physical means or chemical decomposition. A pure substance always has a definite and a constant composition. A mixture is a physical combination which is made up of two or more kinds of pure substances in which each of the substance retains its own chemical identity in the compound.

Uranium is a chemical element with the symbol of U for its representation and the atomic number of 92. Uranium element is a silvery-grey metal in the actinide series of the periodic table of elements. A uranium atom has both 92 protons and 92 electrons, of which 6 of these electrons are valence electrons.

Therefore, the correct option is A.
