547 kilometres, or 340 miles
<span>Net charge of the object = 0.500 ÎĽc
The charge of electron = -1.602 x 10^-19 C
Calculating the net change in the number of electrons = 0.5 x 10^-6 / -1.602 x 10^-19 = - 3.12 x 10^12
The negative sign implies the number of electrons that needs to be removed that is 3.12 x 10^12</span>
Answer:
Explanation:
Neurons communicate via both electrical signals and chemical signals. The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.
The electrical signal travels down the axon to the axon terminals where it tells the vesicles to release the neurotransmitters into the synaptic cleft which travel to the receptors of the receiving cell which releases the second messengers
Answer:
voltmeter (C. Volts)
Explanation:
The amount of electrical potential is measured by voltmeter. Electrical potential is the amount of work needed to move a unit electric charge from a reference point to the specific point in an electric field. <u>The SI unit of electrical potential is Volt</u>.

Answer:
The displacement of the spring due to weight is 0.043 m
Explanation:
Given :
Mass 
Kg
Spring constant 
According to the hooke's law,
Where 
force, 
displacement
Here,
( 
)
N
Now for finding displacement,
Here minus sign only represent the direction so we take magnitude of it.
m
Therefore, the displacement of the spring due to weight is 0.043 m
