Answer:
The resultant force on the boat is 5,000 N
Explanation:
Given;
the forward thrust on the boat, Ft = 35,000 N
water resistance on the boat, Fw = 20,000 N
Air resistance on the boat, Fa = 10,000 N
The forces opposing the boat motion will be negative, while the force pushing the boat forward will be positive
The resultant force on the boat, Fr = Ft - Fw - Fa
Fr = 35,000 N - 20,000 N - 10,000 N
Fr = 35,000 N - 30,000 N
Fr = 5,000 N
Therefore, the resultant force on the boat is 5,000 N
Answer:
Explanation:
Fuses and circuit breakers helps to:
protect equipment by stopping the flow of electric current; protect your house from fire
GFCI helps prevent electric shocks in a house:
GFCI outlets prevent electrocution if you are touching a wet appliance
Three 3ohms resistors in series would give you give a combined resistance of:
Resistance = (3+3+3)ohms = 9ohms
Answer:
The correct option is;
Sphere I is positively charged and sphere II is negatively charged
Explanation:
The charging of the spheres by induction is achieved by introducing a charge to the metal spheres that are insulated from the ground to prevent loss of charge by placing them on insulating stand
The two spheres are brought into contact by the connection of a conducting wire between the spheres I and II
The presence of the positively charged sphere III draws attracts electrons towards sphere II while the net positive charge moves towards sphere I
While the spheres I and II are still polarized, the conducting wire is removed while the presence of sphere III continues to keep sphere II negative compared to sphere I
After removing the connecting wire, sphere III is removed leaving the excess negative charge on sphere II and the excess positive charge on sphere I
The net charges then evenly redistribute themselves on each sphere creating two oppositely charged spheres.
Answer:The answer is when a metal plate is pressed against a fast spinning piece of steel hard enough to stop it. i know this because I just took a test and got this question and got it write
Explanation:
C is the correct answer beacause it shows where it is happening in this cas “here”.
