The formula written in the 3rd line above the picture is WRONG. Don't use it. Use the formula the way it's printed in the picture.
V = d / t
That means Speed = (distance) / (time)
The question tells us that v = 330 m/s
So you write 330 m/s in the equation in place of 'v', like this:
330 m/s = (distance) / (time)
The question also tells us that the time is 0.4 second
So you write 0.4 sec in place of 'time', like this:
330 m/s = (distance) / (0.4 second)
Finally, you take this, and multiply each side of the equation by (0.4 sec). Then it'll say
distance = (330 m/s) x (0.4 second)
As soon as you do that one single multiplication there with your pencil or your calculator, you'll have the distance.
This is either the 2nd or 3rd time you've posted this same exact question since last weekend. It can be solved THIS time exactly like the answers that were posted those other times.
The DOT in the picture is marked for the wrong choice. Use the formula that's printed in the picture, not copied above it.
Answer:
7500000 metres
Explanation:
1 kilometre = 1000 metres
so 7500 kilometres would equal to 7500000 metres
El peso anywhere = (mass) x (gravity there). Gravity en la Tierra = 9.81 m/s^2. Gravity en la Luna = 1.62 m/s^2.
Answer:
P=1113.35 psi
Explanation:
For tank 1
V₁= 6.25 L
P₁=1759 psi
For tank 2
V₂=6.25 L
P₂=467.7 psi
Lets take final pressure is P
The final volume V= 6.25 + 6.25 L = 12.5 L
P V = V₂P₂+V₁P₁
Now by putting the values
P V = V₂P₂+V₁P₁
P x 12.5 = 6.25 x 467.7+6.25 x 1759
P=1113.35 psi
So the final volume of the system will be 1113.35 psi.
Answer:
To provide electrical interlocking
Explanation:
Electrical interlocking involves interconnecting the motor circuit in a manner that the second motor will not start until the first one begins, same goes for the third motor which would not run unless the second one runs and it continues in that sequence.
