Answer:

the length of resultant vector is 5 inches

Explanation:

In the attachment, you will see X vector along the X axis and Y vector along the Y direction. Let the resultant vector be denoted by R

The resultant vector always start from the tail of first vector and ends at the head of second vector.

Since it is a right angled triangle, so the result of resultant vector is found by using Pythagoras theorem i.e.

R^{2} =X^{2} +Y^{2}

So, when we plug in the values of X = 48 and Y = 14

R^{2} =48^{2} +14^{2}

x^{2} =2500\\R=\sqrt{2500} \\R=5

Therefore, the length of resultant vector is 5 inches.

Can someone help with physics
Naily [24]

Answer:

50m/s, 187.5m

Explanation:

Consider unit analysis:

m/s² = m/(s×s)

This can be read as "meters per second, per second". From fundamental kinematics, meters per second is the same as saying velocity.

Velocity is being increased per second, and this is called acceleration:

a = v/t, where a is acceleration, v is change of velocity and t is change of time. "Change" is represented by a triangle called delta and (delta)A = A2 - A1

From the question, we have the variables:

a = 5m/s²

(delta)v = v2 - 25m/s

(delta)t = 5s (initial time is 0)

a = v/t

(5m/s^2)=v/5s

25m/s = v2 - 25m/s

50m/s = v2

The final velocity of the vehicle is 50m/s.

A formula exists to find displacement with regards to acceleration:

d=v(initial) × t +1/2 × a × t²

d=25m/s × 5s + 1/2 × 5m/s² ×(5s)²

d=125m+1/2×125m

d=125m+62.5m

d=187.5m

The distance travelled by the vehicle is 192.5m.

<em>One of the most important skills you can have in any science is unit analysis. Treat meters, seconds, moles, etc as </em><em>values</em><em> when doing </em><em>calculations</em><em> </em><em>and see if you get the result you're looking for.</em>

Mars2501 [29]

Answer:

No

Explanation:

Electric potential is the work done to bring a unit of charge (1 C) from infinity to a point inside an electric field.

Electric potential energy of a charge q is the energy required to keep it in an electric potential V. Electric potential energy is given by,

U = qV

Hence even if the two charges are on an equipotential surface (surface where the potential is the same at all points), the potenial energy will be different if the magnitude or nature of the charges are different.
