Answer:

3.

Explanation:

If the astronaut in the video wanted to move upward, he should throw the object downward because according to Newton’s third law, the object will then exert a force on him in the opposite direction (i.e., upward). hence, option (3) is correct.

Newton's Third Law states that if object A exerts a force on object B, then object B must apply a force to object A that is equal in magnitude and directed in the opposite direction.

This law represents a specific symmetry in nature: forces always exist in pairs, and no body can exert a force without also being subjected to one.

Hence, if the astronaut in the video wanted to move upward, he should throw the object downward and  the object will then exert a force on him in the opposite direction (i.e., upward).

Answer:

0.05s

Explanation:

frequency = speed / wavelength = 20/1 = 20Hz. Thus period = 1/f = 1/20 = 0.05 s

This question involves the concepts of wave speed and wavelength.

The period of the wave is "0.05 s".

The wave speed is given in terms of wave frequency and wavelength as follows:

[tex]v=f\lambda\\\\f=\frac{v}{\lambda}[/tex]

where,

Therefore,

[tex]f=\frac{20\ m/s}{1\ m}\\\\[/tex]

f = 20 Hz

Now, the period of the wave is the reciprocal of the frequency of the wave:

[tex]Period = T=\frac{1}{f}\\\\T=\frac{1}{20\ Hz}[/tex]

T = 0.05 s

Answer:

The magnitude of the coefficient of kinetic friction is approximately 1.304 × 10⁻⁵

Explanation:

The given parameters are;

The time it takes for the box to stop, "t" = 600 seconds

The distance the box moves before coming to a stop, "d" = 23 meters

The work done by the friction force to stop the block = The kinetic energy lost by the box

The work done by the friction force to stop the block = [tex]\mu _k[/tex]·m·g·d

The kinetic energy change of the block = 1/2·m·u²

Where;

g = The acceleration due to gravity = 9.8 m/s²

m = The mass of the box

[tex]\mu _k[/tex] = The coefficient of kinetic friction

d = The distance travelled by the block = 600 m

u = The initial velocity of the block

∴ [tex]\mu _k[/tex]·m·g·d = 1/2·m·u²

[tex]\mu _k[/tex]·g·d = 1/2·u²

[tex]\mu _k[/tex] = 1/2·u²/(g·d) = 1/2·u²/(9.8 × 23) = u²/450.8

∴  [tex]\mu _k[/tex] = u²/450.8...(1)

The kinematic equation of motion of the block can be presented as follows;

v = u - a·t

Where;

v = The final velocity = 0 m/s (The block slides to a stop)

u = The initial velocity

a = The acceleration of the block (the minus sign indicates that the block's velocity is decreasing)

t = The time of motion of the block = 600 seconds

Therefore, by substituting the above values, we have;

0 = u - 600·a

∴ u = a·600

The kinematic equation of motion for the distance moved by the block, "s" can be expressed as follows;

s = u·t - 1/2·a·t²

Where;

s = The distance moved by the bloc = 23 meters

∴ 23 = a·600·600 - 1/2·a·600² = 360,000·a - 1/2·a·360,000 = 180,000·a

a = 23/(180,000)

u = 600 × (23/(180,000)) = 23/300

The initial velocity, u = 23/300 m/s

From equation (1), we have;

[tex]\mu _k[/tex] = u²/(450.8) = (23/300)²/450.8 = 23/1764000 ≈ 1.304 × 10⁻⁵

The magnitude of the coefficient of kinetic friction, [tex]\mu _k[/tex] ≈ 1.304 × 10⁻⁵

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer:

  63.4 °C

Explanation:

If we assume the "fixed points" are 0 °C and 100 °C, then the thermometer reading as a function of actual temperature can be described by a linear equation that must have (0, -0.5) and (100, 106) as solutions. We can use these points in the 2-point form of the equation for a line:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (106 -(-0.5))/(100 -0)(x -0) -0.5

  y = 106.5x -0.5

Then, for x = 60, the thermometer reading is expected to be ...

  y = 106.5×60 -0.5 = 63.4 . . . °C

Explanation:

The talk test would be readily available to me at the the least cost.

The talk test is about the easiest way that one can monitor intensity as they exercise. Because the only thing needed here is the ability to talk and to breathe.

The intensity lies on if one can talk and breathe at the same time. The harder one exercises, the more breathless they become and they find it difficult to talk.

Answer:

D

Explanation:

It's quite simple actually, you see, what light years basically means is how many years light takes to travel from point a to point b. So here it says that a galaxy is 200 million light years away. So since that light is 200 million years away, it would take 200 million years until that light reaches us.

Answer:

42 °

Explanation:

From the question given above, the following data were obtained:

Force (F) = 45 N

Workdone (Wd) = 50 J

Distance (d) = 1.5 m

Angle (θ) =.?

Angle at which the box is pulled can be obtained as:

Wd = Fd × Cos θ

50 = 45 × 1.5 × Cos θ

50 = 67.5 × Cos θ

Divide both side by 67.5

Cos θ = 50 / 67.5

Cos θ = 0.7407

Take the inverse of Cos

θ = Cos¯¹ 0.7407

θ = 42.2 ≈ 42 °

Thus, the angle at which the box is pulled is approximately 42 °.

where F = gravitational force  = ?

G = gravitational constant = [tex]6.674\times 10^{-11} Nm^2kg^{-2}[/tex]

[tex]m_1[/tex] = mass of sun = [tex]1.99\times 10^{30}kg[/tex]

[tex]m_2[/tex] = mass of saturn = [tex]5.68\times 10^{26}kg[/tex]

r = distance between sun and saturn = [tex]1.43\times 10^{12}m[/tex]

[tex]F=\frac{6.674\times 10^{-11}Nm^2kg^{-2}\times 1.99\times 10^{30}kg\times 5.68\times 10^{26}kg}{(1.43\times 10^{12}m)^2}[/tex]

[tex]F=3.69\times 10^{-90}N[/tex]
