Answer:
Sorry this isn’t going to be any help. You don’t have any statement that I’m able to see.
Explanation:
The statement above is FALSE.
The right hand rule is used in physics to predict the direction of the force on a charged object moving in a MAGNETIC FIELD. The right hand rule is used to relate the relationship between the magnetic field and the forces that are exerted on the moving objects in the field. Using the right hand rule, for a positively charged object that is moving in an electric field, the pointer finger will point in the direction the charged object is moving, the middle finger will point in the direction of the magnetic field and the thumb will point in the direction of the magnetic force that is pushing the charged object.
Answer: Hydrogen atoms and oxygen atoms
Explanation:
The H stands for Hydrogen and there is two of those and the O is Oxygen and there is one of them giving you H2O
Answer:
a)P= -4800 i
b)F= 0
Explanation:
Given that
r = (4570-160 t) i + 2930 j + 130 k
We know that velocity is rate of change of the space vector.
V= dr/dt
r = (4570-160 t) i + 2930 j + 130 k
dr/dt= -160 i + 0 + 0
dr/dt= -160 i
V= -160 i
It means that velocity is in only x-direction
We also know that acceleration is the rate of change of velocity .
a= dV/dt
V= -160 i
dV/dt=0
So we can say that acceleration is zero.
a= 0
From Second law of Newton'
Force = Mass x acceleration
F= 300 x 0
F= 0
We know that linear momentum P
P = m V
Given that m= 300 kg
P = 300 x (-160 i)
P= -4800 i
