A bicyclist steadily speeds up from rest to 6.00m/s in 7.30s.

How far did she travel during this time?

Answer:

There is lots of evidence to support it, is the correct answer

The reason why evolution is regarded as a scientific theory is because there are lots of scientific evidences to support it.

Evolution refers to the scientific thinking that complex life forms came out of simple life forms. The complex sequence of events that occurred during the transformation of simple life forms to complex life forms are described by the theories of evolution.

Question:-

Convert 4cm to m

Solution:-

Lets do

First note down the below formula

[tex]\boxed{\sf 1m=10^{2}cm}[/tex]

Then

[tex]\boxed{\sf 1cm=10^{-2}cm}[/tex]

Now we are given 4cm

So convert

[tex]\\ \sf\longmapsto 4\times 10^{-2}m[/tex]

If we simplify to decimal

[tex]\\ \sf\longmapsto 4cm=0.04m[/tex]

Hence done .

A. The S.I unit of mass is kg . therefore we have to convert 4000g into kg from gram

i.e 4000g = 4 kg

B. The S.I unit of length is meter. so we have to convert 2.4 km into meters,

i.e 2.4 km = 2400 m

#A

[tex]\boxed{\sf 1kg=1000g}[/tex]

[tex]\\ \sf\longmapsto 4000[/tex]

[tex]\\ \sf\longmapsto \dfrac{4000}{1000}[/tex]

[tex]\\ \sf\longmapsto 4kg[/tex]

#B

[tex]\boxed{\sf 1km=1000m}[/tex]

[tex]\\ \sf\longmapsto 2.4km=2.4(1000)[/tex]

[tex]\\ \sf\longmapsto 2400m[/tex]

When a car is traveling north, its acceleration vector can point south when it is slowing down.

A vector quantity has both magnitude and direction. The direction of a vector is always shown by the direction to which the arrow points.

If the car is travelling north, the direction of the acceleration vector will continue to point northwards.

However, when the car slows down, the direction of the accelerating vector will now point southwards.

Answer:

C

Explanation:

Options A and B are not even pointing in the direction as the vectors in the question so they shouldn't even be considered.

Option C looks like the closes since vectors A and B are pointing in a similar direction (negative x-axis)

The best representation for the resultant vector representing the resultant R=A+B would be option C because the result is represented by the closing side of the triangle, therefore the correct answer would be C.

The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.

Examples of vector quantities are displacement, velocity acceleration, force, etc.

As given in the problem we have to find out the resultant vector from the sum of vector A and vector B,

The resultant of the vector can be calculated with the help of the triangle law of the vector addition in which the sum is given by the closing side of the triangle.

Thus, the correct answer is option C.

The work-energy theorem explains the idea that the net work - the total work done by all the forces combined - done on an object is equal to the change in the kinetic energy of the object. After the net force is removed (no more work is being done) the object's total energy is altered as a result of the work that was done.

This idea is expressed in the following equation:

is the total work done

is the change in kinetic energy

is the final kinetic energy

is the initial kinetic energy

High pressure squeezes the hydrogen atoms together. They must be within 1x10-15 meters of each other to fuse. The sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core. We must squeeze hydrogen atoms together by using intense magnetic fields, powerful lasers or ion beams.

The  magnitude of their resultant vector is 4.6 meters/seconds

Since we are to add the  velocity vectors in order to  find the magnitude of their resultant vector.

Hence:

Resultant vector magnitude=5.8 meters/seconds + (1.2 meters/seconds)

Resultant vector magnitude=5.8 meters/seconds-1.2 meters/seconds

Resultant vector magnitude 4.6 meters/seconds

Inconclusion The  magnitude of their resultant vector is 4.6 meters/seconds
