Answer:
the answer would be A. electricity don't specify the direction of any cardinal points the flow of charges moves.
Answer:
minimum two photogate
Explanation:
The photogate allows us to activate the measurement of time, so we must place at least two of them, one at the beginning of the movement to measure the initial time and another at the end of the movement to measure the final time, of course we must have measured the distance. This gives us the average speed between the two photocells
For measurements with more changes curves, slopes, one photogate must be placed at the beginning of the curve or slope and another at the end.
When a small cart collide with a large mass then during collision they must be in contact with each other for some interval of time
During this contact interval we can say they will exert normal force on each other
This normal force is always equal and opposite on two balls which means this force will follow Newton's III law
It will be same in magnitude but opposite in the direction
So here correct answer would be
<u><em>They both experience the same magnitude of the collision force.</em></u>
Answer:
1.4 billion light years away
Explanation:
v = Recessional velocity = 30000 km/s[/tex]
= Hubble constant = ![\frac{65}{3.2\times 10^6}\ ly](https://tex.z-dn.net/?f=%5Cfrac%7B65%7D%7B3.2%5Ctimes%2010%5E6%7D%5C%20ly)
D = Distance to the galaxy
According to Hubble's law
![v=H_0D\\\Rightarrow D=\frac{v}{H_0}\\\Rightarrow D=\frac{3\times 10^{4}}{65}\times 3.2\times 10^6\\\Rightarrow D=1476923076.92307\ ly\\\Rightarrow D=1.4\times 10^9\ ly](https://tex.z-dn.net/?f=v%3DH_0D%5C%5C%5CRightarrow%20D%3D%5Cfrac%7Bv%7D%7BH_0%7D%5C%5C%5CRightarrow%20D%3D%5Cfrac%7B3%5Ctimes%2010%5E%7B4%7D%7D%7B65%7D%5Ctimes%203.2%5Ctimes%2010%5E6%5C%5C%5CRightarrow%20D%3D1476923076.92307%5C%20ly%5C%5C%5CRightarrow%20D%3D1.4%5Ctimes%2010%5E9%5C%20ly)
The galaxy is 1.4 billion light years away
<u>Answer</u>
2.65 quarts
<u>Explanation</u>
1 quart = 0.943 liters
To find the how many quarts are there in 2.50 litres we divide the 2.50 litres with 0.943 litres.
Number of quarts = 2.50/0.943
= 2.651113468
To the nearest hundredths the answer = 2.65 quarts
