Answer:
The distance of the object to the center of the earth increases.
Explanation:
The acceleration due to gravity on Earth is given by:
where
G is the gravitational constant
M is the Earth's mass
r is the distance of the object from the Earth's centre
We notice that:
- g does not depend on the mass of the object
- g is inversely proportional to r
This means that if the distance of the object from the Earth's centre increases, g decreases. So, the correct option is
The distance of the object to the center of the earth increases.
Answer:
Two non-perpendicular vectors will not form a right triangle. Yet it is possible to force two (or more) non-perpendicular vectors to be transformed into other vectors that do form a right triangle. The trick involves the concept of a vector component and the process of vector resolution.
Answer:
Technician B is correct
Explanation:
Electrical Switches makes or brakes the flow of signal (current or voltage) in a circuit.
The Technician B that says the switch contacts are closed is correct because it is until when the circuit is continues that voltage flows across the switch and voltmeter will read the amount of voltage present in the circuit. This simply means closed circuit.
Technician A is not correct because when the switch contacts are open, voltage does not flow and no reading will be measured.
Answer: 4,58 C and 0.12 C
Explanation: Considering the Coulomb force given by:
F=(k*q1*q2)/d^2= (9*10^9*q1*q2)/ (0.1)^2 (1)
so replacing the given values and considering also that the total charge is 4.7C this q1+q2= 4.7 C (2)
From (1) and (2) we can find the charges in each sphere.
