If you are driving 100 km/h along a straight road and you look to the side for 1.6 s , how far do you travel during this inatten

denis23 [38]

Answer:

The distance traveled is 44.45 m

Solution:

As per the question:

Average speed, $\bar{v} = 100\ km/h$

Time, t = 1.6 s

Now, convert the average speed into m/s:

1 km = 1000 m

1 h = $60\times 60 = 3600\ s$

To calculate the distance traveled:

Now,

$100\ km/h = \frac{100\times 1000}{3600} = 27.78\ m/s$

We know that:

Speed, $\bar{v} = \frac{distance,\ d}{time,\ t}$

Thus

$d = \bar{v}t$

$d = 27.78\times 1.6 = 44.45\ m$

You are given three pieces of wire that have different shapes (dimensions). You connect each piece of wire separately to a batte

VikaD [51]

Answer:

$R_3 < R_1 < R_2$

Explanation:

The resistance of a wire is given by:

$R=\frac{\rho L}{A}$

where

$\rho$ is the resistivity of the material

L is the length of the wire

A is the cross-sectional area of the wire

1) The first wire has length L and cross-sectional area A. So, its resistance is:

$R_1=\frac{\rho L}{A}$

2) The second wire has length twice the first one: 2L, and same thickness, A. So its resistance is

$R_2=\frac{2\rho L}{A}$

3) The third wire has length L (as the first one), but twice cross sectional area, 2A. So, its resistance is

$R_3=\frac{\rho L}{2A}$

By comparing the three expressions, we find

$R_3 < R_1 < R_2$

So, this is the ranking of the wire from most current (least resistance) to least current (most resistance).

A man pushes a box along a flat, frictionless surface using a force of 500 N. The box was moved a distance of 2.5 m. The actual

andrey2020 [161]

Answer:

Workdone = 1250Nm

Explanation:

Given the following data;

Force, F = 500N

Distance, d = 2.5m

Workdone is given by the formula;

$Workdone = force * distance$

Substituting into the equation, we have

$Workdone = 500 * 2.5$

Workdone = 1250Nm

Therefore, the actual work done by the worker is 1250 Newton-meter.

4. Inertia is directly related to A. Mass B. Mice C. Movement

Soloha48 [4]

A. Mass

Explanation:

Inertia is a property that is directly related to mass of a body. It can be defined as a property that causes a body to resist change in its state of motion.

Newton's first law of motion is known as the law of inertia.
The law state's that "an object will continue to be at rest or in uniform motion unless if it is being acted upon by an external force".

Inertia is related to force and it can be calculated using the expression below:

Inertia = m x a

where m is the mass of the body

a is the acceleration of the body

From this, we see that the more the mass of a body, the more its inertia and its reluctance to change its state of motion.

Therefore mass is directly related to inertia.
