If you traveled to Mars, your mass would be exactly, precisely equal to your mass on Earth, PROVIDED you did not relieve the boredom of space travel by eating too many astronaut steaks along the way.

The only things that can affect your mass are your personal diet, exercise, sleep, and stress habits.  

Your mass has nothing to do with gravity. Your WEIGHT has.

Answer:

299 792 458 m / s

Explanation:

Answer: 13.46 m/s

Explanation:

Initial velocity V1 = 5.82 m/s

acceleration A = 2.35m/s^2

Time taken T = 3.25s

Final velocity V2 = ?

Recall that acceleration is the rate of change of velocity per unit time i.e acceleration = (V2 - V1)/T

2.35m/s^2 = (V2 - 5.82 m/s) / 3.25s

cross multiply

2.35m/s^2 x 3.25s = (V2 - 5.82 m/s)

7.6375m/s = V2 - 5.82 m/s

V2 = 7.6375m/s + 5.82m/s

V2 = 13.46 m/s

Thus, the car final velocity is 13.46 m/s

Answer:

The final velocity is 13.5m/s

Explanation:

a = (v-u)/t

2.35 = (v-5.82) / 3.25

7.6375 = v - 5.82

v = 7.6375 + 5.82

v = 13.5 m/s

Answer:

Braking distance of vehicle is 9.97 m

Explanation:

It is given initial velocity of the vehicle u = 13.4 m/sec

Acceleration of the vehicle [tex]a=-9m/sec^2[/tex]

As the vehicle finally stops so final velocity of the vehicle v = 0 m/sec

We have to find the braking distance s

From third equation of motion

[tex]v^2=u^2+2as[/tex]

[tex]0^2=13.4^2+2\times -9\times s[/tex]

s = 9.97 m

So braking distance of the vehicle is 9.97 m

Answer: 4.41 joules

Explanation:

Given that:

work is done by gravity = ?

Mass of pine cone (m) = 50g

Convert mass in grams to kilograms

Since 1000g = 1kg

50g = (50/1000) = 0.05kg

Height of tree (h) = 9 m

Apply the formula for work,

Work = mass x acceleration due to gravity x height

Acceleration due to gravity has a value of 9.8m/s^2

Work = mgh

Work = 0.05kg x 9.8ms^2 x 9m

Work = 4.41J

Thus, 4.41 joules of work is done by gravity.

4.5 J

Answer:

C. Seed C germinates more with more water.

Explanation:

In this experiment, the seed (seed C) was subjected to certain conditions and the result is what has been presented for us to make an inference.

We observe the following from the information given us:

I. the same seeds were used for the experiment

II. the same heat medium of 24 °C was used for all the seeds

III. different daily amount of water was supplied the seeds - 90 ml, 50 ml and 10 ml

From the experiment, we have this result:

the seed that was watered with 10 ml daily did not sprout anything, the seed that was watered with 50 ml daily yielded 12 sprouts while the seed that was watered with 90 ml daily yielded 16 sprouts

When we consider the amount of water given the seed & the produce of the seed, it is safe to conclude that with increase in daily water, there is increase in the number of sprouts by the seed

Hence, C. Seed C germinates more with more water is the correct answer

The given experiment shows that Seed C's germination is directly proportional to the amount of water it receives. More water results in more sprouts.

From the given experiment results, the conclusion can be drawn that Seed C germinates more with more water. This is evident as the seed sprouted 16 times with a daily water method of 90 mL, 12 times with 50 mL, and not at all with 10 mL. So, the amount of sprouts is directly proportional to the amount of water provided, the more the water, the more the sprouts. This supports the option that Seed C germinates more with more water. Also, the heat was kept constant to ensure that it doesn't affect the experiment results.

Answer:

The force between the two charges will be 13.22N.

Explanation:

The force between the two charges is given by Coulombs law which says

[tex]F = k\dfrac{Q_1Q_2}{R^2}.[/tex]

In our case

[tex]Q_1= 0.00045C[/tex],

[tex]Q_2 = 0.0000032C[/tex],

[tex]R = 0.99m[/tex].

therefore,

[tex]F = (9*10^9)\dfrac{(0.00045C)(0.0000032C)}{(0.99m)^2}.[/tex]

[tex]\boxed{F=13.22N}[/tex]

Hence, the force between the two charges will be 13.22N.

The iron ball is suspended from a box that floats in water. The box has a height of 5.00 cm, a face area of 10.0 cm ​ 2 ​ , and a density of 0.30 g/cm3, and 2.00 cm of its height is above the water surface. What’s the radius of the ball? Hints: ❏ Identify all forces acting on the box and write Newton’s second law. ❏ The box is stationary, which means the forces (including buoyant force) are balanced. You can use this to find tension in the rope. ❏ Identify all forces acting on the ball and write Newton’s second law. ❏ Iron ball is stationary, which means the forces (including buoyant force) are balanced.

Answer: 2.7 x 10^5 joules

Explanation:

Given that:

Time taken = 3 minutes

convert time in minutes to seconds

(Since 1 minute = 60 seconds

3 minutes = 3 x 60 = 180 seconds)

Power of toaster = 1500 watt

Work done by the toaster = ?

Recall that power is the rate of work done per unit time

i.e Power = work/time

work = Power x Time

Work = 1500 watt x 180 seconds

Work = 270000J

Place the result in standard form

270000J = 2.7 x 10^5J

Thus, 2.7 x 10^5 joules of work is done by the toaster.

Answer:

1.44 X 10^-4J

Explanation:

V=w/q =605/sc=12V

The energy required to move a 4.00-micro coulomb charge through a potential difference of 36.0 volts will be 1.44 X 10⁻⁴ J.

The amount of work performed in an electrical field to move a unit charge from one location to another is defined as the electrical potential difference.

The given data in the problem is;

W is the energy =?

q is the charge = 4.00-microcoulomb

V is the potential difference = 36.0 volts

The electric potential is the ratio of electric potential energy and charge.

[tex]\rm V= \frac{W}{q} \\\\\ W=Vq \\\\ W= 36.0 \times 4.00 \times 10^{-6} \\\\ W=144 \times 10^{-6} \\\\ W=1.44 \times 10^{-4}[/tex]

Hence the energy required will be 1.44 × 10⁻⁴ J.

The speed of the players just after the collision is (D) 0.81 m/s

Given that the mass of the fullback is m = 88kg

mass of the opponent, M = 97 kg

speed of the fullback, u = 5 m/s

speed of the opponent, U = 3 m/s

In an inelastic collision, the two bodies move together at the same speed and the total momentum of the system remains conserved.

Let the final speed be v, then by conserving the momentum we get:

mu - MU = (m + M)v

Since the opponent must be moving in opposite direction to the fullback, therefore his momentum is -MU.

88×5 - 97×3 = (88 +97)v

149 = 185v

v = 0.81 m/s

So both the players move with a speed of 0.81 m/s

When this occurs, the Moon, the Sun and Earth don't align in a perfectly straight line, and the Moon casts only the outer part of its shadow on Earth. This happens when only a portion of the Sun is blocked by the Moon. It occurs when the observer is within the penumbra.

Explanation:

If the hydroxide ion (OH-) concentration is greater than the hydronium ion (H3O+) concentration, then the nature of the solution would be basic, therefore the correct answer is option B.

A chemical compound is a combination of two or more either similar or dissimilar chemical elements.

If the hydroxide ion (OH-) concentration is equal to the hydronium ion (H3O+) concentration then the nature of the solution would be neutral.

The correct response is option B because the nature of the solution would be basic if the concentration of hydroxide ions (OH-) is higher than that of hydronium ions (H3O+).
