Answer:

5 N

Explanation:

Given that,

A large bar magnet of mass 0.4 kg exerts a 5 N force on a small bar magnet (mass of 0.1 kg) located 20 cm away.

We need to find the force exerted by the small bar magnet on the large one.

We know that, every action has an equal and opposite reaction. Both action and reaction occur in pairs. The force acting on one object to another is same and in opposite direction on the other object.

Hence, the force exerted by the small bar magnet on the large one is also 5 N.

Answer:

Following are the answer to this question:

Explanation:

Formula:

$D(PC) =\frac{1}{parallax}\\\\D(av)=D(PC) \times 20.626\ J$

Calculating point A:

when the value is $0.38$

$\to 0.38 \toD(PC)= \frac{1}{0.38}\\\\$

$=2.632$

$\to D(a.v) = \frac{1}{0.38} \times 206265\\$

$=542,802.6$

Calculating point B:

when the value is $0.75$

$\to D(PC)=\frac{1}{0.75}$

$=1.33$

$\to D(a.v) = \frac{1}{0.75} \times 206265\\$

$=275,020$

Calculating point C:

when the value is $0.28$

$\to D(PC)=\frac{1}{0.28}$

$=3.571$

$\to D(a.v) = \frac{1}{0.28} \times 206265\\$

$=736660.7$

Calculating point D:

when the value is $0.42$

$\to D(PC)=\frac{1}{0.42}$

$=2.38$

$\to D(a.v) = \frac{1}{0.42} \times 206265\\$

$=490910.7$

Calculating point E:

when the value is $0.31$

$\to D(PC)=\frac{1}{0.31}$

$=3.226$

$\to D(a.v) = \frac{1}{0.31} \times 206265\\$

$=665370.97$

how many days does it take a team of drivers to drive a truck california and back to lansing if the drivers average 15m/s includ

malfutka [58]

4days and 12hours

Explanation:

Given parameters:

Average speed = 15m/s

Distance = 1800 miles

Unknown:

Number of days = ?

Solution:

Speed is the rate of change of distance with time;

Speed = $\frac{distance}{time}$

Since the unknown is number of days, it is a measure of time:

Time = $\frac{distance }{speed}$

The distance from California to Lansing is 1800miles. The journey takes the truck drivers to and fro. It is a two way trip;

Total distance = 1800 miles x 2 = 3600miles

We need to convert miles to meters since that is the unit we can conveniently work with;

1 mile = 1609.34m

3600 miles = 3600 x 1609.34

= 5793638m

Inputting the values in the equation:

Time = $\frac{ 5793638}{15}$ = 386242.53s

Now we need to convert to day;

In a day, = 60 x 60 x 24 = 86,400s

1 day = 86400s

Therefore;

The number of days = $\frac{386242.53}{86400}$ = 4.47days

This implies that it will take them 4 days and approximately 12 hours.

Question 1 (1 point)

MatroZZZ [7]

Answer:

The work done by the frictional force is 600J.

Explanation:

The work $W$ done by the frictional force is

$W= Fd$ .

Now, $F = 60N$ and $d =10m$ ; therefore,

$W= (60N)(10m)$

$\boxed{W = 600J.}$

Hence, the work done by friction is 660J.
