Answer:
The correct answer is:
(a) 0
(b) 0.5 m/s
(c) 7740 N
(d) 0
Explanation:
The given values are:
mass,
m = 3000 kg
Tension,
T = 7,200 N
Angle,
= 30°
(a)
Even as the block speed becomes unchanged, the kinetic energy (KE) will adjust as well:
⇒
By using the theorem of energy, the net work done will be:
⇒
(b)
According to the question, After 0.25 m the block is moving with the constant speed
= 0.5 m/s.
(c)
The given kinetic friction coefficient is:
u = 0.3
The friction force will be:
=
On substituting the values, we get,
=
=
=
=
(d)
On including the friction,
The net work will be:
⇒
Answer:
A & B are correct
Explanation:
Certain automotive sensors like crank shaft position sensor uses a.c. while most automotive components require DC to work properly through the battery which is incorporated with an alternator to keep it charged through a diode while continual supply of DC is sustained.

Any of three muscles in each buttock that move the thigh, the largest of which is the gluteus maximus.
<span>After entering the loop, it should use the correct list size and the loop will be affected if the remove call changes the size of the list.
If lst is an Arraylist the running time of removefirsthalf is O (n^2). So when the beginning is removed the next element will move forward.
If lst is a LinkedList which is a dynamic structure the running is O (n) for removefirsthalf</span>
