Answer:
See the explanation below
Explanation:
The watt (the power) is equal to the relationship between the work and the time in which that work is performed.
where:
W = work [J] (units of Joules)
t = time [s].
Now 1000 [W] are equal to 1 [kW]
And 1000000 [W] are equal to 1 [MW]
The horsepower is the unit of power in the imperial system of units.
And 745.7 [W] are equal to 1 [Hp]
Answer:
B) 2 times what it now is
Explanation:
The acceleration due to gravity at the surface of the Earth is given by
where
G is the gravitational constant
M is the mass of the Earth
R is the Earth's radius
In this problem, the mass of the Earth is doubled:
M' = 2M
while the radius remains the same:
R' = R
so the new acceleration due to gravity would be
so, the acceleration due to gravity would become twice the current value.
Note also that the value of g does not depend on the mass of the objects involved.
Hello,
To solve we need to know the formula for speed
The formula is D/T=S (Distance of time=speed)
Now all we have to do is plug in the numbers.
20/40= 1/2 or 0.5
SO the speed is 0.5 m/s
Have a great day!
Independent variable- a variable (often denoted by x ) whose variation does not depend on that of another.
Hope this helps :)
Answer:
a.)
Explanation:
a.) is the only possible answer because it is in m/s^2 which are the units for acceleration, and you already know the magnitude of acceleration will be 5 given the other options.
