Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of oneâs birth. The on
ly known force that a planet could exerts on us is gravitational, so if there is anything to astrology we should expect this force to be significant. Required:
a. Calculate the gravitational force, in Newtons, exerted on a 4.1 kg baby by a 120 kg father who is a distance of 0.18 m away at the time of its birth.
b. Calculate the force on the baby, in Newtons, due to Jupiter (the largest planet, which has a mass of 1.90Ã10^27 kg if it is at its closest distance to Earth, 6.29Ã10^11 m away.
c. What is the ratio of the force of the father on the baby to the force of Jupiter on the baby?
GREATER than 1 g/cm. 3, it will SINK in water. LESS than 1 g/cm3, it will FLOAT in water. If an object's density is: Density of Object > Density of Liquid.
Electrical power is defined as the product of voltage by current.
where:
P = power = 1150 [W]
V = voltage = 230 [V]
I = current [amp]
Now replacing:
A 15 [amp] fuse must be used. Always the fuse must be larger than the operating current, to protect the equipment from very high currents. above 15 [amp]
As per energy conservation we can say that energy stored in the spring at the position of maximum compression must be equal to the kinetic energy of bullet and block system
