A car, initially traveling at 15 meters per second

Physics
1 answer:
AnnZ [28]3 years ago
3 0
The magnitude of the acceleration of the car is given by:
a= \frac{v_f-v_i}{t}
where
v_i=15 m/s is the initial speed of the car
v_f=25 m/s is the final speed of the car
t=4.0 s is the time it takes for the car to change its speed

Substituting these data into the formula, we find the magnitude of the average acceleration of the car:
a= \frac{25 m/s-15 m/s}{4.0 s}=2.5 m/s^2

therefore, the correct answer is <span>(1) 2.5 m/s^2.</span>

Morgarella [4.7K]

The image shows the correct way of lining up vectors to add them together, that the two arrows lined up one after the other, therefore the correct answer is option B.

<h3>What is a vector quantity?</h3>

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.

Thus, the image shows the correct way of lining up vectors to add them together, that the two arrows lined up one after the other, therefore the correct answer is option B.

Charged particles posses a region of influence also called a (an)
Delvig [45]

Answer:(c)

Explanation:

Charge particle posses a region of influence called a filed i.e. Electric field.

It is a region around the charged particle such that other charge particle experiences force due to this field. The nature of force is decided by the charge on the particle creating an electric field.

For a positive charge, electric field lines emerge out of it, and for a negative charge, it acts as radially inwards.
