Answer:
1) F1
Explanation:
As the air resistant force depends on the speed of object and its orientation as it falls, it does not depend on the mass of the object. Therefore, air resistant force on 1 coffee filter is the same as the air resistant force on 3 coffee filters.
A spaceship on its way to another planet is traveling at a speed of 4200 miles per hour .This in units of millimeters per second will be 1877.568 m/s
Unit refers to the quantity of a constant magnitude, used to measure the magnitudes of other quantities of an identical type
1 mph = 0.44704 m/s
hence , 4200 mph = 0.44704 * 4200 = 1877.568 m/s

Answer:
the current flowing through the filament would be 5 amperes.
Explanation:
we know that according to OHMS law
V=I×R
where i is the current and R is the resistance and V is the voltage
applying the values in the formula
We get I = 5 A.
Homes with multiple bathrooms have outlets connected in series with a red reset button in the system. The reason for this circuit design is to prevent electrocution.
<h3>What is red reset button?</h3>
The water heater's reset switch provided on the upper thermostat of an electric water heater. If the button is on, the switch would have tripped and the reset is required.
To prevent any kind of injury or killing of a person by electric shock is called as the electrocution. This can be prevented only by outlets connected in series with a red reset button.
Thus, the reason for this circuit design is to prevent electrocution.

Answer:
C. Television
Explanation:
Mostly in cathode ray television, a TV has many of different types of capacitors, used as connections between circuits, as timing components and as electronic filters. TV capacitors perform many functions.
capacitor acts as a reservoir for electric charge, storing and releasing electricity in precise amounts.
What is a Capacitor ?
A capacitor is a simple device consisting of a pair of metal foils separated by a thin insulator, such as plastic, used basically for storing charge
