Monoammonium phosphate effectively smothers the fire, while sodium bicarbonate induces a chemical reaction which extinguishes the fire. Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment.
Answer:
The two forces acting on the object are weight due to gravity pulling the object towards earth, and drag resisting this motion. When the object is first released, drag is small as velocity is low, so the resultant force is down. This means the object accelerates towards earth.
Correct option: D. Earthquakes along the San Andreas fault in California.
The earthquakes occur when the two plates collide with each other. Hence, there is contact between the two plates. So, the contact forces are responsible for the earthquakes.
The force responsible for Jupiter's moons to stay in orbit or the high tides occurring on the east coast is the gravitational force, which is not a contact force as there is no contact between Jupiter and its moon or the earth and the moon which is responsible for the high tides.
Moreover, the magnetic force is a non contact force as it attracts the pins from a distance without any contact between them.
Answer:
6m/s
Explanation:
We are to calculate the speed of Monique
Speed = Distance/Time
Given
Distance = 360m
Time = 60secs
Substitute
Speed = 360m/60s
Soeed = 6m/s
Hence she was running at 6m/s
Equation of power in a electrical circuit is given as:
I → Current flowing through the circuit.
R → Resistance of the circuit
We need to calculate power when;
Current (I) = 0.02 A
Resistance (R) = 30 Ω
By substituting values in the equation, we get:
Power in the circuit = 0.012 W
