Answer:
True.
Explanation:
A nanometer is a unit of mass, whereas a nanosecond is a unit of time. To convert 1.3 hours to minute, you would multiply by 1 h / 60 min. Kilometer is a unit of length, whereas kilogram is a unit of mass. True.
Solution
In this question we have given
Charge,
Charge,
Charge,
Distance between Charge and ,d=43cm=.43m
Let the distance between charge and , is x
Therefore,distance between charge and , will be=(.43-x)
We know By Couloms law, Force on Charge due to charge which are seperated by distance d is given by following equation
............(1)
Here, K=
Therefore,
Force on Charge due to charge
..(2)
Similarly,
Force on Charge due to charge
..(2)
In equilibrium condition,
on solving we get
x=.277m
0r x=28cm
The distance between charge and , is 28cm
Answer:
the planet Earth is a good example
Answer:
The magnitude of the force per unit of lenght between the wires are of F/L= 3.17 * 10⁻⁵ N/m.
Explanation:
d=0.0665m
I1=I2= 3.25A
μo= 4π * 10⁻⁷ N/A²
F/L= (μo * I1 * I2) / (2π * d)
F/L= 3.17 * 10⁻⁵ N/m
Answer:
Explanation:
Allison can measure the mass of the rock by using a scale. An electronic beam balance will be able to give her the mass of the rock to a fairly accurate degree.
To go about measuring the volume of the rock, an indirect approach has to be adopted since the rock is not regular in shape. Allison would have to adopt a principle that explains that the volume a solid body displaces when immersed in a pool of liquid, is directly equal to the volume of the solid itself.
This means that if the stone is placed in a beaker of water containing an already measured volume of water, the increase in the volume of the water when the stone is immersed is equivalent to the volume of the stone.
