how can you say metre cube is a derived unit​

Answers

Answer 1

Answer:

The newton (lowercase n!) is a derived unit because its definition consists of multiplication of three defined base units and nothing else. Its meaning is thus derived, not independently defined.

A runner begins from rest at the starting line and travles for 6.5 seconds, a runner reaches a speed of 13.4 m/s what is the runners acceleration?

Answers

The acceleration of the runner in the given time is 2.06m/s².

Given the data in the question;

Since the runner begins from rest,

Initial velocity; [tex]u = 0[/tex]Final velocity; [tex]v = 13.4m/s[/tex]Time elapsed; [tex]t = 6.5s[/tex]

Acceleration of the runner; [tex]a = \ ?[/tex]

Velocity and Acceleration

Velocity is the speed at which an object moves in a particular direction.

Acceleration is simply the rate of change of the velocity of a particle or object with respect to time. Now, we can see the relationship from the First Equation of Motion

[tex]v = u + at[/tex]

Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.

To determine the acceleration of the runner, we substitute our given values into the equation above.

[tex]v = u + at\\\\13.4m/s = 0 + (a * 6.5s)\\\\13.4m/s = a * 6.5s\\\\a = \frac{13.4m/s}{6.5s}\\ \\a = 2.06m/s^2[/tex]

Therefore, the acceleration of the runner in the given time is 2.06m/s².

Hi there!

Recall the equation for the magnetic field of a wire (assuming infinite):

[tex]B = \frac{\mu _0 i_{encl}}{2\pi r}[/tex]

B = Magnetic field (T)
μ₀ = Permeability of Free Space (Tm/A)

i = enclosed current (A)
r = distance from wire (m)

From the equation, we can see that there is a DIRECT relationship between the current and the magnetic field.

Therefore, if the current is increased by a factor of 3, the FIELD will also be increased by a factor of three.

Negative electrons orbiting around atoms in a molecule produce modest magnetic fields surrounding them.

The vector of a magnetic force that acts on a current is opposite to the axis of the electric current and magnetic fields, as per Fleming's left-hand rule.

A sound wave passes from air into water and then into steel. With each change in medium, what happens to the speed of the wave?.

Answers

Answer:

Explanation:

You need to consider the index of refraction.

index of refraction of air: 1.00

index of refraction of water: 1.33

Index of refraction of steel: 2.75681

If the sound wave passed from air into water, it passes from a lower index to a higher index of refraction.

As the wave travels into the more dense medium (higher n), it slows down. Therefore from air to water (lower to higher) it slows down, and from water to steel (n of steel is higher that n of water) therefore it slows down even more.
