Answer: D (doubled)
According to ohm's law
I = V/R ,
V = IR ; R = constant and V is doubled
From the equation
V is directly proportional to the current, and it is given that R is constant ;
2V = 2I. R since R = constant
Hence I is doubled.
You will get 20460000 as your answer which is broken down into, 2.046 x 10^7 as your number has to be between 1-10.
Answer:
there is no diagram, but i can try to help
Explanation:
strong winds bonding together (i.e hot and cold) help form the tornado, depending on the weather depends on how long it can go on, if more hot and cold are feeds into it, it will get faster and last longer. it is just like dust devils, it is wind and dirt mixing to make a tornado, the more wind and dirt the worst it will be
Answer:
20m/s
Explanation:
Given parameters:
Distance of throw = 50m
Time = 3s
Unknown:
Average speed = ?
Solution:
Average speed is distance divided by time;
Average speed = 
Insert the parameters and solve;
Average speed = 
= 16.66667m/s = 20m/s
Answer:
h = 81.63 m
Explanation:
Given that,
The speed of the car, v = 40 m/s
We need to find the height when the car comes to rest. We can use the conservation of energy to find it i.e.
So, it will reach to a height of 81.63 m and comes to rest.
