Answer:
right
Explanation:
Current flows from the positive (+ve) terminal of the battery to the negative (-ve). This is called conventional current flow.
Therefore, the electrons are negatively charged and want to get away from the Negative Terminal and go to the Positive Terminal, Hence the electrons move from left to right and current flows from right to left.
Well idk if this helps but the formula to solve acceleration is
a=F/m=(100kg)=1.0m/s 2
Answer:
The gauge pressure is
Explanation:
From the question we are told that
The height of the water contained is
The height of liquid in the cylinder is
At the bottom of the cylinder the gauge pressure is mathematically represented as
Where is the pressure of water which is mathematically represented as
Now is the density of water with a constant values of
substituting values
While is the pressure of oil which is mathematically represented as
Where is the density of oil with a constant value
substituting values
Therefore
Answer:
Explanation:
In order to measure the coefficient of friction , we apply external force to move the body . When external force comes in motion , we adjust the external force so that it moves with zero acceleration or uniform velocity . In this case external force becomes equal to kinetic frictional force and then net force becomes zero because
net force = mass x acceleration = m x 0 = 0
Now frictional force = μ mg where μ is coefficient of kinetic friction
so F = μ mg where F is external force applied
μ = F / mg
Hence , to make external force equal to frictional force , it is necessary to make acceleration of body zero .
