7.32652978 × 10∧12 centimetre per (day squared) is the answer by converting  32.2 ft/s^2 to centimeter per day squared

Humans constantly encounter many factors. One g is the usual gravitational acceleration. You must, however, accelerate 9.8 m/s2 upward in order to reach 2g. You will accelerate by 2g as a result of this. While on Earth, we frequently experience more than 1g.

This enables you to calculate the change in velocity in metres per second squared (m/s2).

An informal measurement of force using units of acceleration equal to one g that applies to a body due to acceleration or gravity. A 12 pound item moving at 2 g receives 24 pound of force, for instance.

The value 35.6 have on the measures of central tendency for the data in the left column, as mean will be higher than the median and mode. The correct option is C.

The mean is the average of a set of values in mathematics and statistics. There are several ways to compute the mean, including the simple arithmetic mean, the geometric mean, and the harmonic mean.

To find the mean, add all of the numbers together. The total sum is then divided by the number of scores used. The mean or average of the number set in this example is 6.7.

The value 35.6 has a positive effect on the measures of central tendency for the data in the left column, as the mean is greater than the median and mode.

The potential energy gained is 4550 J.

The potential energy that a huge item has in relation to another massive object due to gravity is known as gravitational energy or gravitational potential energy. When two objects descend toward one another, potential energy associated with the gravitational field is released.

The potential difference is given as:

U = mgh

Where U is the gravitational energy, m is the mass, g is the acceleration due to gravity, and h is the height.

Now, we have

Leopard's mass, m = 65kg

The height of the tree, h = 7 m

Acceleration due to gravity, g = 10N/kg

Therefore,

U = mgh

U = 65 × 7 × 10

U = 65 × 70

U = 4550 J

Thus, the leopard will need 4550 J of gravitational potential energy to climb 7 meters.

The rectangle is four sided which each of the angles of the rectangle adding up to give 360 degrees. It must be noted that the opposite sides of the rectangle are equal to each other.

We have the following information;

Length of the pool = 4(3 feet) = 12 feet

Width of the pool = 3 feet

Force = (mass) x (acceleration)

so

Acceleration = Force / mass

Acceleration = (1400 N) / (70 kg)

Acceleration = 20 m/s²

The mass of the second rocket should be 0.4 kg in order for the acceleration to be half of the first rocket's acceleration.

We know that,

F = m a

where,

F = Force

m = Mass

a = Acceleration

Given that,

[tex]F_{1}[/tex] = 100 N

[tex]m_{1}[/tex] = 0.2 kg

[tex]F_{1}[/tex] = [tex]F_{2}[/tex] = 100 N

[tex]a_{2}[/tex] = [tex]a_{1}[/tex] / 2

[tex]F_{1}[/tex] = [tex]m_{1}[/tex] *  [tex]a_{1}[/tex]

[tex]a_{1}[/tex] = 100 / 0.2

[tex]a_{1}[/tex] = 500 m / s²

[tex]a_{2}[/tex] = 500 / 2

[tex]a_{2}[/tex] = 250 m / s²

[tex]m_{2}[/tex] = 100 / 250

Now;

Work done by the person = mgh =  100.0 kg  * 10 m/s^2 * 10 m = 10000 J

To convert from joules to kcal, we know that;

1 kcal = 4184 J
