Answer:
constructively
6
Explanation:
c = Speed of light =
= Frequency = 1.667 GHz
= Path difference = 1.08 m
Wavelength is given by
Path difference is given by
As the integral multiple of wavelength gives path difference the waves will combine constructively.
The value of m is 6
Answer:
Conduction occurs when two objects at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. ... It is caused by the increased activity or speed of molecules in a substance, which in turn causes temperature to rise accordingly. This process continues until heat energy from the warmer object spreads throughout the cooler object.
Explanation:
C) Energey
A) True
I believe, dont quote me on it
A ground wire provides a conducting path to the earth which is separate and independent from the path of an electrical appliance. Also, a ground wire is an additional pathway for an electric current to safely return to the ground without imposing danger to anyone in the event that a short circuit might occur. This is particularly important for shock hazard since it forces the breaker to trip by supplying a path to the ground if ever a hot wire comes in contact with a metal case of the appliance.
A fuses and circuit breakers limit the current which can possibly flow in a circuit. The metal filament present in the fuse will melt and break the connection. On the other hand, the circuit breaker with its bimetallic strip's heating effect causes a bending and tripping of a spring-loaded switch.
Answer:
1782.7 N/C, downward
Explanation:
Since the charged sphere is in static equilibrium, it means that the electric force acting is balanced with the weight of the sphere, so we can write:
where
m = 3.62 g = 0.00362 kg is the mass of the sphere
g = 9.8 m/s^2 is the acceleration of gravity
is the magnitude of the charge
E is the magnitude of the electric field
Solving for E,
In order for the sphere to be in equilibrium, the electric force must be in opposite direction to the weight, so the electric force must point upward. Since the sphere has a negative charge, the electric field has opposite direction to the electric force: so, the electric field direction is downward.
