Statement:

The electric current passing through a conductor is directly proportional to the potential difference across its ends provided temperature and other physical conditions remain constant.

Explanation:

Current is directly proportional to voltage loss through a resistor. That is, if the current doubles, then so does the voltage. To make a current flow through a resistance there must be a voltage across that resistance. Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R).

V∝I or I∝V⇒V=IR.

Explanation:

Ohm's law states that the current through a conductor is proportional to the voltage across the conductor. This is true for many materials (including metals) provided the temperature (and other physical factors) remain constant. The constant of proportionality, R,R is the resistance and the unit is the ohm, with symbol \Omega,Ω. The relationship can be written as:

V, equals, I, R.

V=IR

where V,V is the voltage across the conductor and I,I is the current flowing through it. If a component is ohmic (it obeys Ohm's Law), then its resistance must be independent of current and voltage.

Answer:

8 seconds

Explanation:

From Newton's second law;

Ft = m(v-u)

F = Force applied

t = time taken

v = final velocity

u  = initial velocity

20 * t = 32 (9 - 4)

20t = 32 * 5

t = 32 * 5/ 20

t = 8 seconds

Hope this helps!

Explanation:

As an object falls, it picks up speed. The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating. An object falling toward earth stop accelerating when it velocity becomes terminal velocity. Or When weight becomes equal to Drag force acting on the object due to air resistance.

Answer:D increases

Explanation:

When sound travels from air into glass, speed of a sound wave increases. Hence option D is correct.

Wave is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down.

Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase.

Phase is the position of a wave at a point at time t on a waveform.

speed of the sound is greatest in solid and it is medium in liquid and lowest in gaseous state.

In this problem sound wave is going from air to glass, it is actually going from gaseous to solid state, as speed of sound is greatest in the solid, speed of the sound increases to 5.640 m/s.

Hence option D is correct.

Answer:

The force of the air on the skydiver's body is:

[tex]F_{air}=637.7\: N[/tex]

Explanation:

Let's recall that when an object reached terminal velocity, the force of the air acting is equal to the weight of the object, so the net force will be zero, that is why the object falls at a constant speed.

Then we have:

[tex]F_{air}=W=mg[/tex]

where:

m is the mass of the skydiver (65 kg)

g is the gravity acceleration (9.81 m/s²)

Therefore, the force of the air on the skydiver's body is:

[tex]F_{air}=65*9.81=637.7\: N[/tex]

Answer:

30,000 kgm/s

Explanation:

m = 1000 kg

v = 30 m/s

Plug those values into the equation:

p = mv

p = (1000 kg)(30 m/s)

p = 30,000 kgm/s

The momentum of a 1000 kg sports car traveling at 30 m/s is 30,000 kgm/s.Linear momentum = Mass x Speed.

The product of an object's mass, m, and its velocity, v, is the vector quantity known as linear momentum. It is represented by the letter "p," which is also used to denote momentum.

Mass of car = 1000 kg

Speed by which car moves = 30 m/s. The momentum of the car =?

Recall that:

Linear momentum = Mass x Speed

= 1000 kg x 30 m/s.

= 30,000 kgm/s

The sum of an object's mass (m) and velocity (v) is known as the object's linear momentum. An equation can be used to explain this relationship. Momentum is defined as the body's mass times its velocity. P = m times v, etc.

Therefore,  the momentum of a 1000 kg sports car is 30,000 kgm/s if travels at 30 m/s.

Answer:

60m/s

Explanation:

since the object is falling under the influence of gravity, the formula is

v = u +gt

before the fall, the object is at rest then

u = 0m/s

v = 0 + 10×6 because acceleration due to gravity is g which is given as 10m/s2

therefore, v = 60m/s

the way you speak with your entire body

Explanation:

Body language is the way you speak with your entire body. Therefore, the correct option is option D.

Body language refers to a form of communications in which information is expressed or conveyed via bodily behaviors rather than words. Face expressions, body posture, movements, eye movement, touch, and use of space are examples of this type of behavior.

Although the phrase "body language" is typically used in reference to people, it can also be used in reference to animals. Kinesics, another name for the research of body language, is related. Although facial expression is a crucial component of communication, much of it occurs subconsciously. Body language is the way you speak with your entire body.

by transferring heat from the tropics to the colder climates

The statement which best describes how the ocean convection cycle impacts different climates is by transferring heat from the tropics to the colder climates. Thus, the correct option for this question is C.

The ocean convection cycle may be characterized as a type of methodology through which the mesoscale ocean circulation and large, strong winds mix layers of water at different depths.

During this cycle, when one part of a fluid is heated, the temperature difference causes by transferring heat from the tropics to the colder climates fluid to move in a current or defined direction. As the heated fluid rises, it is replaced by a cooler fluid, which is sometimes referred to as a convection cycle.

Therefore, transferring heat from the tropics to the colder climates is the process that best describes how the ocean convection cycle impacts different climates. Thus, the correct option for this question is C.

BALL

Explanation:

what is BALL/ SOCCER BALL

Answer:

The kinetic energy is 16 joules.                        

Explanation:

Kinetic energy (E) is given by:

[tex] E = \frac{1}{2}mv^{2} [/tex]

Where:

m: is the mass

v: is the speed

When the kinetic energy is 4 joules, the speed of the object is:

[tex] v_{1}^{2} = \frac{2E_{1}}{m} = \frac{8}{m} [/tex]                         

Now, if the speed is increased twice then we have:

[tex] E_{2} = \frac{1}{2}mv_{2}^{2} = \frac{1}{2}m(2v_{1})^{2} = \frac{1}{2}m[4(\frac{8}{m})] = 16 J [/tex]

Therefore, the kinetic energy is 4 times the initial value.

Answer:

negative particles

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.

Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Hence, an object is most likely to become electrically charged by gaining or losing negative particles.
