Answer:
Explanation:
Use the velocity formula to solve
In this question, you are given velocity 
, and you are given a distance, 
. Time in this question is what you'll need to find.
Start by rearranging the velocity formula, to isolate for t.
Start by multiplying both sides by t
Then divide both sides by v.
Now that you've isolated for time, sub in your values and calculate.
Answer:
meter i guess
Explanation:
cause for length,the SI unit is meter
The concept required to solve this problem is hydrostatic pressure. From the theory and assuming that the density of water on that planet is equal to that of the earth 
we can mathematically define the pressure as
Where,
= Density
h = Height
g = Gravitational acceleration
Rearranging the equation based on gravity
The mathematical problem gives us values such as:
Replacing we have,
Therefore the gravitational acceleration on the planet's surface is 
Answer:
88 Watts
Explanation:
From the question given above, the following data were obtained:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = IV....... (1)
From ohm's law,
V = IR ........ (2)
Substitute the value of V in equation (2) into equation (1)
P = IV
V = IR
P = I(IR)
P = I²R
With the above formula (i.e P = I²R), we can obtain the power lost to heat as follow:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = I²R
P = 20² × 0.22
P = 400 × 0.22
P = 88 Watts
Thus, the power lost to heat is 88 Watts.
I can answer it in the comments, but can i ask what i’m supposed to do exactly? i remember learning about this stuff but i need the instructions.
