Explanation:

Answer:

D. You would weigh the same on both planets because their masses

and the distance to their centers of gravity are the same.

Explanation:

The above statement is true due to the fact that, the weight and masses of the individual are same in direct comparison with the distance to their center of gravity. If the weight and masses are not same, then there would have been a significant difference between the two planet.

Answer:

They are also called the gas planets because they consist mainly of hydrogen, or the giant planets because of their size. These planets usually have complicated system of many moons and often even rings of ice and/or dust. There are four Jovian planets in the Solar System: Jupiter, Saturn, Uranus and Neptune.

Answer:

The correct option is;

The assertion is correct, but reason wrong

Explanation:

The question is with regards to the relationship between work, energy, power, and velocity

The mass of each of the persons running up the staircase = Different

The time it takes each person to run up the stairs = Equal time

Let, 'm₁' and 'm₂' represent the mass of each of the persons that ran up the stairs and m₁ > m₂

Let 't' represent the equal time it takes then to run up the stairs

Let 'h' represent the height of the stairs

The energy, 'E', it takes to run up the stairs is equal to the potential energy, P.E., obtained at the top of the stairs

P.E. = m·g·h

Where;

m = The mass of the person at an elevated height

g = The acceleration due to gravity = Constant

h = The height reached above ground level

Given that the height reached is the same for both of the persons, we have

For m₁, P.E.₁ = m₁·g·h and for m₂, P.E.₂ = m₂·g·h

Therefore, where, m₁ > m₂, we have;

P.E.₁ > P.E.₂

∴ E₁ > E₂

Power, 'P', is the rate at which energy is expended

∴ Power, P = E/t

∴ P₁ = E₁/t  > P₂ = E₂/t

Therefore, the person with the greater mass, 'm₁', uses more power than the person of mass 'm₂', in running up the stairs

Therefore, the assertion is correct

The average velocity, vₐ = (Total distance traveled, d)/(Total time taken, t)

Given that the distance, 'd', covered in running up the stairs by both persons is the same, and the time it takes them to complete the distance, 't', is also the same, we have;

The average velocity of the person with the greater mass m₁ is the same as the average velocity of the person with mass, m₂

Therefore, the reason is wrong

The answer is that the assertion is correct, but reason wrong

Answer:

Impulse is force multiplied by time; and together, the product must be 1 unit. A collision with soft ground will result in the 1 unit of impulse by a larger time and a smaller force (compared to the small time and a large force for the hard floor).

Answer:

O2 has two more electrons compared to N2, with extra 2 electrons in the higher energy anti-bonding orbitals known as Diradical. These electrons have higher energy and are unpaired; therefore, O2 is more reactive

Explanation:

Answer:

O B. Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3.

Explanation:

The total work done to move the lift to this height if, A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m, is 15000 Joules.

When an object is moved over a distance by an external force, at least a portion of that force must be applied in the direction of the displacement. This is known as work in physics.

Given:

A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m,

Calculate the total force as shown below,

Total force = Lift weight + man weight

Total force = 300 + 950

Total force = 1250 N

Calculate the work done as shown below,

The work done = Total force × displacement by total force

The work done = 1250 × 12

The work done = 15000 Joules

Thus, the total work done is 15000 joules.

Answer:

Mass of the truck is [tex]1154[/tex] Kg

Explanation:

As we know that

Force is the product of mass and acceleration.

F = m * a

Here acceleration, a [tex]= 39[/tex]  m/s^2

Force, F [tex]= 45000[/tex] Newton

Mass = [tex]\frac{F}{a}[/tex]

Mass

[tex]= \frac{45000}{39} \\= 1154[/tex] Kg

Answer:

650 N / 0.10 m2 = 6500 Pa

Explanation:

The pressure that could be exerted on the ground with each top should be 6,500 Pa

Given that,

We need to determine the pressure.

So, the following formula should be used.

[tex]= \frac{Mass}{area}\\\\= \frac{650}{0.10} \\\\[/tex]

= 6,500 Pa

Therefore we can conclude that the pressure that could be exerted on the ground with each top should be 6,500 Pa.
