Using the formula for word
W=Fd
We can find work because we have the distance and force
d=1 km= 1000m
F= 34 N
Thus W= 34(1000)
W= 34,000 J
PS I'm super close to the next rank, I need one more "Brainiest" solution. If you could I would be very grateful
Answer:
8.8 cm
31.422 cm/s
Explanation:
m = Mass of block = 0.6 kg
k = Spring constant = 15 N/m
x = Compression of spring
v = Velocity of block
A = Amplitude
As the energy of the system is conserved we have
Amplitude of the oscillations is 8.8 cm
At x = 0.7 A
Again, as the energy of the system is conserved we have
The block's speed is 31.422 cm/s
Answer:
Explanation:
His Kinetic energy = 1/2 m v^2
v = 5 m/s
m = 75 kg
Ke = 1/2 75 * 5^2
Ke = 937.5 Joules
This will be converted to PE when he reaches the maximum height he reaches. In other words KE = PE
PE = m * g * h
m = 75
g = 9.81
h = ?
PE = 937.5
937.5 = 75 * 9.81 * h
937.5 = 735.75 * h
937.5/735.75 = h
h= 1.27 meters
Answer:
mass of 1 mole of person is 6.02 times more than the mass of earth
Explanation:
Number of atoms in 1 mole = Avagadro Number
now we know that average mass of one person = 60 kg
so total mass of 1 mole of persons
now the comparison of this mass of 1 mole of person with the mass of earth is as following
So mass of 1 mole of person is 6.02 times more than the mass of earth
