Explanation:
It is given that,
Radius of the circular orbit, 
Speed of the electron, 
Mass of the electron, 
(a) The force acting on the electron is centripetal force. Its formula is given by :
(b) The centripetal acceleration of the electron is given by :
Hence, this is the required solution.
Opposite attract , this is the magnetic south pole
option (b) ✔
<span>This would be chemical energy that is
converted to heat. The heat from the wick melts the wax which gets
absorbed in the wick and then gets burnt (which is really oxidation) to
produce heat energy.</span>
Answer:
2nd answer 3.2m/s is a scalar l, all others are vectors.
Explanation:
In order to be considered as a vector a certain quantity must have both a magnitude and a direction.
The most common example is velocity. It has both magnitude and direction, like the 1st and the last answers.
The 3rd answer is an acceleration. It is also given with its direction. So we have to consider it also as a vector.
But 2nd answer has no direction mentioned, so it is considered as a scalar.
Answer:
P = 400248 [Pa]
Explanation:
We can calculate the hydrostatic pressure exerted by a column of liquid by means of the following equation.
where:
Ro = density = 1020 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = depth = 40 [m]
Therefore:
![P=1020*9.81*40\\P=400248 [Pa]](https://tex.z-dn.net/?f=P%3D1020%2A9.81%2A40%5C%5CP%3D400248%20%5BPa%5D)
