Distance = 170 km Displacement = 30 km East Speed = 56-2/3 km/hr Velocity = 10 km/hr East
Answer:
the final velocity of the bus is -20 m/s.
Explanation:
Given;
initial velocity of the bus, u = 20 m/s
deceleration of the bus, -a = 8 m/s²
time of motion, t = 5 s
The final velocity of the bus is calculated as;
v = u + at
v = 20 + (-8 x 5)
v = 20 - 40
v = -20 m/s.
Therefore, the final velocity of the bus is -20 m/s.
Answer:
B. counterclockwise
Explanation:
We can solve the problem by using the right-hand rule:
- put your thumb finger of the right hand in the same direction of the current in the wire (upward)
- wrap the other fingers around the thumb
- the direction of the other fingers will give the direction of the magnetic field lines
By doing these steps, we see that the other fingers form concentric circles in a counterclockwise direction (seen from above), so this is the direction of the magnetic field lines.
Answer:
peripheral heart action
Explanation:
The peripheral heart action is a variation of circuit training that alternates upper body and lower body exercises throughout the circuit.
Peripheral heart action practice is a method of interval bodybuilding training that was coined in the 1960s by former AAU Mr. America and Mr. Universe Bob Gajda. Most sources say that Gajda has always credited Arthur H. Steinhaus to create the concept behind PHA.
D, the plant takes Solar/Light energy and converts it into chemical energy.
