<span>It also doubles
The gravitational force between two masses is expressed as:
F = G*m1*m2/r^2
where
F = Force between the two masses
m1 = Mass of object 1
m2 = Mass of object 2
r = distance between centers of object 1 and object 2
G = Gravitational constant
The exact values of G, m1, m2, and r don't matter since all except for m1 is held constant. And when m1 suddenly doubles, the force attracting the two object to each other also doubles.</span>
Answer:
Explanation:
power of a heating element = V² / R where V is voltage and R is resistance
putting in the values
5200 = 75² / R
R = 1.082 ohm
Formula for resistance
R = ρ L / S , ρ is resistivity , L is length and S is cross sectional area
1.082 = 5 x 10⁻⁷ x L / (3.83 x 10⁻⁶)
L = 8.29 m
b )
power of a heating element = V² / R , R is new resistance
5200 = 120² / R
R = 2.77 ohm
R = ρ L / S , ρ is resistivity , L is length and S is cross sectional area
2.77 = 5 x 10⁻⁷ x L / (3.83 x 10⁻⁶)
L = 21.22 m
The answer for the above statement is:
a. longitude
Explanation:
Longitude is that the measure of however way a definite place is found a way west and east from the longitude. Great circle determines the geographical zone of a selected location. Whereas latitude affects the temperature of the situation, longitude doesn't do a lot to have an effect on the temperature.
Answer:
Linear momentum= Mass*Velocity
P=mv
P=60*10
P=600Kg m/s
GPE= height x mass x gravitational field strength
5 x 10 x 9,8=490J
