On Earth, a scale shows that you weigh 360 N. What is your mass?

Answer:

Acceleration, a = 0.375 m/s²

Explanation:

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

[tex]a = \frac{v - u}{t}[/tex]

Where,

Given the following data;

Initial velocity, u = 0m/s

Final velocity, v = 0.3m/s

Time, t = 0.8secs

Substituting into the equation, we have;

[tex]a = \frac{0.3 - 0}{0.8}[/tex]

[tex]a = \frac{0.3}{0.8}[/tex]

Acceleration, a = 0.375 m/s²

Therefore, the the magnitude of the vacuum's acceleration is 0.375 m/s²

Take the direction of motion to be the positive direction. The crate slows to a rest from 30.0 m/s in a matter of 5.0 s, so it has acceleration a such that

0 = 30.0 m/s + a (5.0 s)   →   a = -6.0 m/s²

At the moment its speed is 0, the crate has a net force of s + f acting in negative direction, where s and f denote the magnitudes of the stopping force (s = 250 N) and the friction force, respectively. By Newton's second law, we have

(-s) + (-f) = (100 kg) (-6.0 m/s²)

250 N + f = 600 N

f = 350 N

The friction force is proportional to the normal force by a factor of µ, the coefficient of kinetic friction. There is no movement in the up- and downward directions, so Newton's second law says

(-w) + n = 0

where w is the weight of the crate and n is the magnitude of the normal force. So

n = w = (100 kg) (9.80 m/s²) = 980 N

Then

f = µ n

350 N = µ (980 N)

µ = (350 N) / (980 N) ≈ 0.357

Answer:

All cells come from pre-existing cells

Explanation:

Rudolf Virchow, a German Physician, stated the theory that all cells arise from pre-existing cells. He used this theory to explain disease pathology at the cellular level. His work helped clarify that diseases occur not at tissue or organ level, but at the cellular level. This resulted in more accurate diagnosis of diseases by other scientists.

His legacies includes being among the first to use animals in his research, first to name numerous diseases and also the creation of many medical terms still in use today.

Answer:  The cell shrinks

Explanation:   Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). So if you get thirsty at the beach drinking seawater makes you even more dehydrated.

================================================

Work Shown:

The values we're working with are

[tex]v_i = 0 = \text{ initial velocity}\\\\v_f = 16 = \text{ final velocity}\\\\t = 4 = \text{ change in time}\\\\a = \text{ unknown } = \text{ acceleration}\\\\[/tex]

We'll plug those into the kinematics formula below to solve for 'a'

[tex]v_f = v_i + a*t\\\\16 = 0 + a*4\\\\16 = 4a\\\\4a = 16\\\\a = \frac{16}{4}\\\\a = 4\\\\[/tex]

Joe's acceleration is 4 m/s^2

This means that every second, Joe's velocity is increasing by 4 m/s.

---------------------------

To check our answer, we can see that

Time 0 = Velocity 0

Time 1 = Velocity 4

Time 2 = Velocity 8

Time 3 = Velocity 12

Time 4 = Velocity 16

This confirms our answer.

Answer:

magnitude =

Explanation:

Given an initial velocity of 11200m/s, and acceleration of -70m/s^2, we are told to find the magnitude of the velocity in 10s.

In general, magnitude is defined as the numerical value or quantity of a variable. In physics, magnitude refers to the total measure(length) of distance covered.

Answer:

Mass, M = 0.75kg

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Given the following data;

Kinetic energy = 150J

Velocity = 20m/s

Making mass the subject formula;

[tex] M = \frac{2K.E}{V^{2}}[/tex]

Substituting into the equation, we have;

[tex] M = \frac{2*150}{20^{2}}[/tex]

[tex] M = \frac{300}{400}[/tex]

Mass, M = 0.75kg

Answer:

yoga postures and breathing techniques in Hatha yoga purify the physical body.

Explanation:

The right option must be option (B).

Since the orbit of the earth is only 3% oblate, it is closer to a circle.

According to Kepler's laws of planetary motion:

So according to Kepler's law, it would seem that the answer must be option A. And it can be the right choice generally.

But the orbit of earth is only 3% oblate, which means it is only 3% an ellipse, so the orbit of the earth is closer to a circle. So the right option must be option B.

Answer:

5.88 m/s

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 7 m/s

Acceleration (a) = –0.6 m/s²

Distance (s) = 12 m

Final velocity (v) =.?

We, can determine how fast the sprinter is running when he crosses the goal line as follow:

v² = u² + 2as

v² = 7² + (2 × –0.6 × 12)

v² = 49 + (–14.4)

v² = 49 – 14.4

v² = 34.6

Take the square root of both side

v = √34.6

v = 5.88 m/s

Therefore, the sprinter is running at a speed of 5.88 m/s when he crosses the goal line.
