Answer:equal mass
Explanation:the mass of both is 5kg
Answer:
m/s
Explanation:
Assumptions: 0° is true North, and 90° is east (along the x-axis).
To solve this problem we must use the expression:

Where
is the velocity in the y-direction (East),
is the total velocity in the direction which the aircraft is travelling, and
is the direction the aircraft is travelling (angle from the y-axis).
Using the equation above, we obtain the y-component of velocity
m/s which is rounded to 227 m/s (due to the number of significant figures in the question).
12m/s
Explanation:
Given parameters:
Distance run by student = 120 meters
Time = 10 seconds
Unknown:
Speed = ?
Solution:
Speed is the rate of change of distance with time:
Speed = 
Now input the parameters:
Speed =
= 12m/s

Answer:
a.Electric force exerted on one charged sphere, by another charged sphere.
Explanation:
Coulomb's Law describes the electric force between two objects. It is given by the following formula:

The magnetic field surrounding a current carrying conductor is described by Ampere's Law.
Amount of heat generated by a high current flow in a resistor can be described by P = VI
Voltage induced in a coil by a constant magnetic field is described by Faraday's Law.
Answer:
a.0.5 Io
Explanation:
The fraction of light passing through the first polarizer will be

The fraction of light passing through the second polarizer will be

where
= Angle between the filters
here, as the transmission directions are parallel to one another


Hence,
will pass through both filters
