Answer:

3 m\s Ans .....

Explanation:

Solution:

v = (1.5)(2)

v = 3 m\s Ans ........

Answer:

acceleration = 0.013 m/s²

Explanation:

formula for acceleration is

a = (v-u) / t

a= (0.7-0.3) / 30

= 0.013

The acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Acceleration is defined as the change in velocity of a body with respect to time. Mathematically:

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

v is the final speed = 0.7m/s

u is the initial speed = 0.3m/s

t is the time taken = 30seconds

Substitute the given values into the formula:

[tex]a=\frac{0.7-0.3}{30}\\a=\frac{0.4}{30}\\a = 0.0133m/s^2[/tex]

Hence the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Answer:

frequency = 5 /s

period = 0.5 s/

Explanation:

number of revolution = 10+10/2 = 20/2 = 10

frequency = n/t = 10/5 = 5 /s

period = t/n = 5/10 = 0.5s

Answer:

newton's first law of motion

Explanation:

this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it so...

isn't this similar to the law of inertia?

yes it is

Answer:

see below

Explanation:

a wave means one complete wave which is 1 period

so a) 5 complete waves

wavelength is the shortest distance between any two points in phase

so wavelength = 1 CM

amplitude of a wave is the maximum displacement of a particle from its rest position

so amplitude = 3 CM

Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not.

Ultraviolet Rays in the electromagnetic Spectrum Ultraviolet rays are a kind of electromagnetic radiation that extends from the visible light spectrum to the X-ray area.

Harmful rays have a long-term effect on humans, causing skin and eye problems. It is also a source of Vitamin C.

Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not,

Hence light from the ultraviolet flashlight harden the filling when light from the lamp does not.

Answer:

F = m x a

Explanation:

F = force

m = mass of an object

a = acceleration

Answer:

Explanation:

Formula

F = m * a

Givens

F = 4900

a = 7 m/s^2

Solution

4900 = m * 7         Divide by 7

4900/7 = m

700 kg = m

Explanation:

The distance between two electrons, d = 0.10 m

We need to find the magnitude of the electrostatic force on an electron by another electron.

The electrostatic force between two charges is given by :

[tex]F=k\dfrac{q_1q_2}{d^2}[/tex]

Substitute all the values,

[tex]F=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(0.1)^2}\\\\F=2.30\times 10^{-26}\ N[/tex]

So, the magnitude of the electrostatic force between two electrons is [tex]2.30\times 10^{-26}\ N[/tex].

It is a force imposed by one charge on another as a result of the field. The magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge is inverse of the square of the radius.

The electrostatic force is determined by the charge potency of each charge as well as the separation distance between them.

The given data in the problem is;

q=q₁=q₂ is the electric charge = 1.6×10⁻¹⁹C

r is the distance between the two charge=0.10 m

The formula for the electrostatic force is given by;

[tex]\rm F=\frac{ Kq_1q_2}{r^2} \\\\ \rm F=\frac{ 9\times 10^9 \times(1.6\times 10^{-19})^2}{(0.1)^2}\\\\ \rm F =2.30 \times 10^{-26} \ N[/tex]

Hence the magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

Technically yes, it does help those objects not to float away, but that is false. gravity is not the factor that lets us watch tv, talk on the phone etc.

Gravity helps us watch television, talk on the phone, and use the Internet. This is true statement.

The goal of satellites is to achieve balance. They rotate around the globe quickly enough to avoid being entirely drawn down into the planet's center of gravity, yet slowly enough to avoid drifting out into space.

When a satellite is travelling at the right speed, the earth's gravitational attraction is just strong enough to keep it in place. A satellite must move quicker to maintain orbit the nearer it is to the earth's surface. Additionally, satellites' orbits are circular or elliptical due to the continual pull of the curved surface of the planet.

Therefore, gravity plays a crucial role in our daily lives, whether it's keeping us anchored to the planet's surface or keeping the satellites we use to communicate and learn more about our environment in orbit.
