According to Newton's first law of motion, what would happen to a car traveling at a constant velocity of 55 MPH to the west in

the absence of an unbalanced force?
Physics
1 answer:
mart [117]3 years ago
6 0

Explanation:

  • Newton's first law of motion says that an object will be at rest or it will be in motion until an unbalanced force acts on it.
  • In this case, a car traveling at a constant velocity of 55 mph to the west in the absence of an unbalanced force.
  • It would mean that the car will continue to move with a constant velocity of 55 mph to the west due to Newton's first law of motion.

What's the difference between electromagnetic waves and electromagnetic spectrum?
White raven [17]
The difference between the two is, well for one

Spectrum: The entire range that the "<em>waves" </em>could be such, as visible light, x-ray's and so on.

Waves: These are different because they aren't telling you or showing the entire spectrum just which they length that they are.

<em>It may confuse you but it makes sense to me (Sorry)</em>

A delivery truck travels 2.8 km North, 1.0 km East, and 1.6 km South. The final displacement from the origin is ___km to the ___
34kurt

Answer:

The final displacement from the origin is <u>1.6</u> km to the <u>NE</u>

Explanation:

The directions in which the delivery truck travels are;

1) 2.8 km North = 2.8·\hat j, in vector form

2) 1.0 km East = 1.0·\hat i, in vector form

3) 1.6 km South = -1.6·\hat j, in vector form

Therefore, to find the final displacement, Δx, of the delivery truck, we add the individual displacements as follows;

Final displacement, Δd = 2.8·\hat j + 1.0·\hat i +(-1.6·\hat j) = 1.2·\hat j + 1.0·\hat i

Final displacement, = 1.0·\hat i + 1.2·\hat j

Where;

Δx = The displacement in the x-direction = 1.0·\hat i

Δy = The displacement in the y-direction = 1.2·\hat j

The magnitude of the resultant displacement vector is given as follows

\left | d \right | = √((Δx)² + (Δy)²) = √(1² + 1.2²) ≈ 1.6 (To the nearest tenth)

The magnitude of the resultant displacement vector ≈ 1.6 km

The direction of the resultant vector is positive for both the east and north direction, therefore, the direction of the resultant vector = NE

Therefore, the resultant displacement of the delivery truck is approximately 1.6 km, NE from the origin.

Measuring the volume of a ball that is 24cm across how can you set up an equation
BigorU [14]
The volume of every sphere is

           Volume = (4/3) (pi) (radius)³

When you say "across", I think you mean the diameter of the ball.
The radius is half of the diameter = 12 inches.

         Volume = (4/3) (pi) (12 inches)³

                       = (4/3) (pi) (1,728 cubic inches)

                       =    7,238.2 cubic inches .  (rounded)
