Answer:
0.21 m/s/s.
Explanation:
Whenever there is an action force acting on a body, there will be a reaction force.
Here the force with which the astronaut throws the tool is given as 16 N.
Force is measured in newtons and is equal to the rate of change of momentum.
Since the astronaut has a mass, she experience a reaction force. It is given by F = ma, according to Newton's 2nd law.
16 = 75 a
⇒ Acceleration = a = F/m = 16/75 = 0.21 m/s/s
Answer:d
Explanation:
Given systems are state of matter and do not contain any heat instead Heat is required to change Phase or raise the temperature of the particular system.
For example 600 kg of ice at
Heat Required to convert it to water at is
Where L=latent heat of Fusion
Answer:
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.
Explanation:
Answer:
8 (maybe 18)
Explanation:
Depends on whether you have the d orbitals. If not, it's 8, and it's 18 including the d orbitals
To solve this problem it is necessary to apply the concepts related to Gauss's Law.
Gauss's law establishes that the flow of certain fields through a closed surface is proportional to the magnitude of the sources of that field inside the same surface.
Mathematically it can be expressed as,
Where
A = Surface area of Gaussian surface
Q = Charge enclosed by Gaussian surface
= Permittivity of free space
E = Electric Field
Our values are given as
Therefore replacing at our equation we can find Q,
Therefore the magnitude of the charge is
