Weight = Mass × Gravity

Mass = 15 kg

Gravity = 9.8 m/s^2

Weight = 15 kg × 9.81 m/s^2 = 147 N

Your answer would be C. 147 N

15 kg × 9.81 m/s^2 = 147 N

We know that either team is winning which means that the cumulative forces (sum of each girl force) on both teams are equal.

This means,

$250 + 250 + 250 + 250 = 260 + 260 + 260 + x$

being x the force of the fourth girl on the east team.

Solving to x, you get

$x = (250 + 250 + 250 + 250) - (260+260+260)x = 1000 - 780x = 220$

The fourth girl on the east is pulling with a force of 220N.

4. What's the voltage drop if V, = 56 V, V2 = 35 V, and V3 = 3 V

Murrr4er [49]

Answer:

The correct option is A. 18 V

Therefore,

$V_{1}=18\ V$

Explanation:

Given:

Total Voltage,

V = 56 V,

Voltage drop

$V_{2}=35\ V$

$V_{3}=3\ V$

To Find:

$V_{1}=?$ (Assumed ,as it is not given clearly in the question)

Solution:

So in series combination total Voltage is given as

$V=V_{1}+V_{2}+V_{3}$

Substituting the values we get

$56=V_{1}+35+3\\\\V_{1}=56-38=18\ V$

Therefore,

$V_{1}=18\ V$

How long will a bus take to travel 150 km at an average speed of 40 km h?

yan [13]

225 mins long will a bus take to travel 150 km at an average speed of 40 km h

Since the average speed is 40km/h it means

40 km can be travelled by it in 1 hour

1 km can be travelled by it in 1/40 hour

So 150km can be travelled by it in 150/40 hours or 225 mins.

By formula time=distance/speed=150/40=3.75hours

Speed = Distance/Time – This tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance. Time = Distance / Speed, as the speed increases the time taken will decrease and vice versa.
