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:Visible light is a small part of the electromagnetic spectrum. The spectrum covers everything from gamma rays, x-rays, visible light, infrared, microwave and radio waves. Each part of the spectrum, including the different colors of visible light, have different wavelengths (the space between each wave).

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

Answer:

2¹⁶ⁿ

Explanation:

2ⁿ¯⁴ × 16¹⁺ⁿ / 8¯ⁿ × 4¯⁴ⁿ

The above expression can be simplified as follow:

2ⁿ¯⁴ × 16¹⁺ⁿ / 8¯ⁿ × 4¯⁴ⁿ

Recall:

16 = 2⁴

8 = 2³

4 = 2²

Thus,

2ⁿ¯⁴ × 16¹⁺ⁿ / 8¯ⁿ × 4¯⁴ⁿ

= 2ⁿ¯⁴ × 2⁴⁽¹⁺ⁿ⁾ / 2³⁽¯ⁿ⁾ × 2²⁽¯⁴ⁿ⁾

= 2ⁿ¯⁴ × 2⁴⁺⁴ⁿ / 2¯³ⁿ × 2¯⁸ⁿ

Recall:

Mᵃ × Mᵇ = Mᵃ⁺ᵇ

2ⁿ¯⁴ × 2⁴⁺⁴ⁿ / 2¯³ⁿ × 2¯⁸ⁿ

= 2⁽ⁿ¯⁴⁾⁺⁽⁴⁺⁴ⁿ⁾ / 2¯³ⁿ⁺⁽¯⁸ⁿ⁾

= 2ⁿ¯⁴⁺⁴⁺⁴ⁿ/ 2¯³ⁿ¯⁸ⁿ

= 2⁵ⁿ / 2¯¹¹ⁿ

Recall:

Mᵃ / Mᵇ = Mᵃ¯ᵇ

2⁵ⁿ / 2¯¹¹ⁿ = 2⁵ⁿ¯⁽¯¹¹ⁿ⁾

2⁵ⁿ / 2¯¹¹ⁿ = 2⁵ⁿ⁺¹¹ⁿ

2⁵ⁿ / 2¯¹¹ⁿ = 2¹⁶ⁿ

Therefore,

2ⁿ¯⁴ × 16¹⁺ⁿ / 8¯ⁿ × 4¯⁴ⁿ = 2¹⁶ⁿ

Answer:

"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:

the answer is c

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.

BALL

Explanation:

what is BALL/ SOCCER BALL

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.

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]
