Explanation:

what is BALL/ SOCCER BALL

Answer:

Speed BA = 18 km/hr.

Explanation:

Given the following data;

Speed AB = 30km/hr

Speed BA = x km/hr

Average speed = 24 km/hr

To find the value of x;

Average speed = (Speed AB + Speed BA)/2

Substituting into the equation, we have

24 = (30 + x)/2

48 = 30 + x

x = 48 - 30

x = 18 km/hr

Explanation:

beacuse light is mixture of many different colours,each with different frequency

sunlight contains ultraviolet rays only best describes the forms of electromagnetic waves produced by sunlight. Hence option A is correct.

A fraction of the electromagnetic energy emitted by the sun, including infrared, visible, and ultraviolet light, is known as sunlight. When the Sun is above the horizon, sunlight on Earth is seen as daylight after being dispersed and filtered by the atmosphere. Sunshine, a mix of brilliant light and radiant heat, is what we feel when direct solar radiation is not obstruct by clouds. Sunlight is diffused when it is obstructed by clouds or reflected off of other surfaces. According to sources, the average solar radiation received by each square metre on Earth during a 24-hour period ranges from 164 to 340 watts[1]; according to NASA, this amount represents roughly 25% of the planet's average total solar irradiance.

Sunlight's UV radiation has both favorable and unfavorable impacts on health.

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

Explanation:

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.

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

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]

"solve: given that F -12 N and time 4 seconds and let we have to find out the P.

F = 12 N

t = 4 s

p = ?

F = m×( v - u ) / t

12 = m×v / 4

m×v = 12× 4

p = 48 kg m/s

Linear momentum will be 48 kg m/s.

Answer:

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:

Approximately [tex]1.0\times 10^{3}\; \rm kg[/tex] (assuming that [tex]g = 9.8\; \rm m \cdot s^{-2}[/tex].)

Explanation:

Consider an object of mass [tex]m[/tex] and (relative) height [tex]h[/tex].

The gravitational potential energy (GPE) of this object would be [tex]{\rm GPE} = m \cdot g \cdot h[/tex] (where [tex]g[/tex] denotes the gravitational field strength. Typically,[tex]g = 9.8\; \rm N \cdot kg^{-1}[/tex] near the surface of the earth.)

For the shipping crate in this question:

Rearrange the equation [tex]{\rm GPE} = m \cdot g \cdot h[/tex] to find an equation for [tex]m[/tex]:

[tex]\begin{aligned}m &= \frac{{\rm GPE}}{g \cdot h} \\ &= \frac{266,\!375\; \rm J}{9.8\; \rm N \cdot kg^{-1} \times 26\; \rm m}\\ &= \frac{266,\!375\; \rm N \cdot m}{9.8\; \rm N \cdot kg^{-1} \times 26\; \rm m} \\ &\approx 1.0\times 10^{3}\; \rm kg\end{aligned}[/tex].

Hence, the mass of this shipping crate is approximately [tex]1.0\times 10^{3}\; \rm kg[/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.
