If a vehicle accelerating at 2.7 m/s2what is it's velocity at 20 meters 12.63m/s,1.03m/s,10.39m/s,6.39m/s

netineya [11]

Answer:

The final velocity of the vehicle is 10.39 m/s.

Explanation:

Given;

acceleration of the vehicle, a = 2.7 m/s²

distance moved by the vehicle, d = 20 m

The final velocity of the vehicle is calculated using the following kinematic equation;

v² = u² + 2ah

v² = 0 + 2 x 2.7 x 20

v² = 108

v = √108

v = 10.39 m/s

Therefore, the final velocity of the vehicle is 10.39 m/s.

Two charged particles are placed 2.0 meters apart. The first charge is +2.0 E-6 C, and the second charge is +4.0 E-6 C. What is

Anestetic [448]

The electrical force between the two charges can be calculated as +1.8×10⁻² N and its repulsive.

To find the electrical force, distance = 2 meters

charge q1 = 2×10⁻⁶ C

charge q2 = 4×10⁻⁶ C

<h3>Define coulomb's law and solve with formula.</h3>

The force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between them.

Formula can be written as,

F = K ( q1q2 / r² )

F - electric force

k - Coulomb constant

q1, q2 - charges

r - distance of separation

Substituting the values in the formula,

F = 9 × 10⁹ Nm²/C² ( (2×10⁻⁶ C × 4×10⁻⁶ C) / (2²))

= 0.0179751

F = 1.8 × 10 ⁻² N.

As both the charges q1 and q2 are positive, the charges gets repulsive.

SO, the correct answer is Option A.

uranus is much smaller and less massive than jupiter. uranus rotates on its side, giving it extreme seasons. this may have been

Tresset [83]

The correct statements from the following list about how Uranus is different from Jupiter, and how its rings and moons formed and evolved includes the following:

Uranus is much smaller and less massive than Jupiter.
Uranus's appearance is nearly featureless; very bland.
Uranus has some large moons and rings.
Uranus rotates on its side, giving it extreme seasons. This may have been caused by an impact.

Describe Uranus?

Uranus is described as the seventh planet from the Sun. The name Uranus is a reference to the Greek god of the sky, Uranus, who, according to Greek mythology, was the great-grandfather of Ares, grandfather of Zeus and father of Cronus.

Some known facts about Uranus includes the following:

Uranus is the coldest planet in the Solar System
Uranus orbits the Sun on its side
A Season on Uranus lasts one long day which is equal to 42 years
Uranus is the second-least dense planet.

The unit for IMA is _____. newtons joules meters IMA is unitless

Sonja [21]

The correct answer to the question is unitless i.e the IMA of a mechanical system has no unit.

EXPLANATION:

The IMA of a mechanical system stands for ideal mechanical advantage. It can be defined as the number of times the input or effort force provided to the mechanical system is multiplied under ideal conditions. The ideal conditions means that the system is free from friction, air resistance etc.

Let us consider $d_{i}$ is the distance over which the input force is applied.

Let $d_{0}$ is the distance over which the output force is applied.

The ideal mechanical advantage of the system is calculated as -

IMA = $\frac{d_{i}} {d_{0}}$ .

Both $d_{i}\ and\ d_{0}$ are measured in distance unit.

Hence, IMA is a unitless physical quantity.

If the incident intensity of the light is 26 W/m, what is the intensity of the light that emerges from the filter

REY [17]

47W/ $m^{2}$ is the intensity of the light that emerges from the filter

Use Malus's law, the intensity of the light is,

I= $I_{0}$ , cos² ∅

The intensity of the beam from the first polarizer is equal to the half of

the initial intensity.

$I_{1}$ = $I_{0}$ /2

Substitute the numerical values we get

94 W/m² 2

= 47 W/m²

What is intensity ?

In physics, the power transferred per unit area is known as the intensity or flux of radiant energy, where the area is measured on a plane perpendicular to the direction of the energy's propagation. Watts per square meter (W/m2) and kilograms per square meter (kg/s3) are the units used in the SI system. With waves like acoustic waves (sound) or electromagnetic waves like light or radio waves, intensity is most usually employed to describe the average power transfer across one period of the wave. Other situations where energy is exchanged can also be described in terms of intensity. One could, for instance, figure out how much kinetic energy each drop of water from a sprinkler is carrying.
