On Saturn, the acceleration due to gravity is 11.08 m/s². On Venus, the acceleration due to gravity is 8.87 m/s². For an alien traveling to both planets, which answer is true?

A. On Venus, the alien would have less mass because the gravity is lower on Venus than on Earth.

B. On Venus, the alien would have more mass because the gravity is lower on Venus than on Earth.

C. On Saturn, the alien would weigh than on Earth because the gravity is higher on Saturn than on Earth.

D. On Saturn, the alien would weight less than on Earth because the gravity is higher on Saturn than on Earth.

Answer:

v = 20 m/s

Explanation:

Let's use v = u + at for uniform acceleration.

v = finaly velocity

u = initial velocity

a = acceleration

t = time

Since we start from rest, our initial velocity is zero.

[tex]v = 0 + 4(5)[/tex]

[tex]v = 20 m/s[/tex]

Answer: hope it helps you....

Answer: C

Explanation:

Resistors R1, R2 and R3 are in  parallel so

1/R1 + 1/R2 + 1/R3 = 1 ohm

adding Resistor 'R' make it 2ohm + 1 ohm = 3 ohm

Whereas for current use formula I = V/R

The velocity of the wave having a frequency of 458 Hz and a wavelength of 0.74 m is 338.92 m/s

The velocity of a wave is related to its frequency and wavelength according to the following equation:

Velocity (v) = wavelength (λ) × frequency (f)

v = λf

v = λf

v = 0.74 × 458

v = 338.92 m/s

Thus, the velocity of the wave is 338.92 m/s

Answer:

Condensation is your answer

Explanation:

Condensation is the process of steam rising back into the atmosphere and the steam would be the evaporation "steam" hope this helped

Steam rising from the boiling water causes the whistle sound, which means that the convection part of the water cycle is present here.

The process of convection entails the movement of a heated fluid, such as air or water, in order to transfer heat.

Convection is caused by the fact that most fluids have a tendency to expand when heated, which causes them to become less dense and rise due to the increased buoyancy. The homogeneous heating of air in a heated room or water in a kettle is due to circulation generated by this effect: heated particles expand the area they move in by moving faster against each other, rise, and afterwards cool and close again, increasing density and causing a corresponding sinking.

In forced convection, fluid is carried using mechanisms other than those that result from differences in density with temperature. Examples of forced convection include the air movement by a fan or water by a pump.

Answer:

In short, a force applied to an object at rest causes it to accelerate in the direction of the force.

Explanation:

Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e. to change its velocity, at a constant rate.

Answer:

As the force acting upon an object is increased, the acceleration of the object is increased.

Explanation:

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

‎ㅤ➙ Mechanical Advantage= 1.5

Mechanical advantage allow to perform tasks much easier in terms of the force needed to apply, but must always obey the conservation of energy. Mechanical advantage is the measure of the ratio of output force to input force needed in a system, used to analysis the force in simple machines like livers and pulleys.

Mechanical advantage is given by:

[tex] \qquad\hookrightarrow\quad {\pmb{\sf{MA =\dfrac{Load}{effort} }} }[/tex]

We are provided with:

Therefore,

[tex] :\implies\quad \sf{MA = \dfrac{L}{E} }[/tex]

[tex] :\implies\quad \sf{ MA = \dfrac{6\cancel{00}}{4\cancel{00}}}[/tex]

As a result, if the field lines are close together (that is, the field line density is greater), this indicates that the magnitude of the field is large at that point. If the field lines are far apart at the cross-section, this indicates the magnitude of the field is small. (Figure) shows the idea.
