Answer:
20 m/s
Explanation:
The speed of a wave is given by:
where
is the wavelength
f is the frequency
v is the speed
For the wave in this problem,
f = 10 Hz is the frequency
is the wavelength
So the speed is
a. Calculate the Force Friction
FN
The force of friction is 213.2 N
Explanation:
The frictional force acting on an object sliding on a surface is given by:
where:
is the coefficient of friction
m is the mass of the object
g is the acceleration of gravity
In this problem we have
m = 29 kg
Therefore, the force of friction is

What is the final speed of the car after this work is performed?
Answer:
9.43 m/s
Explanation:
The law of conservation of energy requires that the total energy before and after transformation must be equal. Kinetic energy of car and rocket combined equals the parachute energy and that of car.
Final energy of car will be 66120-36733=29,387 J
Kinetic energy, and making v the subject of the formula then
Where m is the mass and v is velocity.
Substituting 29387 J for KE and 661 kg for m then
appellate jurisdiction
When a court has appellate jurisdiction, then it can hear a case once a lower court has ruled on it. Hence, option B is correct.
The ability of a higher court to consider appealing from a lower court is known as appellate jurisdiction. A higher court has the authority to reconsider rulings and alter their conclusions.
The highestcourt has judicial power over circuit courts, whereas the circuit courts have judicial power over the circuit courts in the federal judiciary. With appellate jurisdiction, the majority of higher courts only review the lower court's judgment to check for any legal mistakes.
The majority of cases that the Highest Court of States decides fall under its appellate authority. It can evaluate the majority of federal court rulings as well as state court rulings affecting constitutional or statutory law. In Article 3, Section 2 of the US Constitution, even the Supreme Court's appellate jurisdiction is discussed.
Therefore, it concludes that appellate jurisdiction is the correct answer.
