Determine the magnitude of force F so that the resultant FR of the three forces is as small as possible.
Kamila [148]

Answer: FR=2.330kN

Explanation:

Write down x and y components.

Fx= FSin30°

Fy= FCos30°

Choose the forces acting up and right as positive.

∑(FR) =∑(Fx )

(FR) x= 5-Fsin30°= 5-0.5F

(FR) y= Fcos30°-4= 0.8660-F

Use Pythagoras theorem

F2R= √F2-11.93F+41

Differentiate both sides

2FRdFR/dF= 2F- 11.93

Set dFR/dF to 0

2F= 11.93

F= 5.964kN

Substitute value back into FR

FR= √F2(F square) - 11.93F + 41

FR=√(5.964)(5.964)-11.93(5.964)+41

FR= 2.330kN

The minimum force is 2.330kN

1. Block A with a mass of 1 kg and block B with a mass of 2 kg lie on a smooth table. You wish to apply a horizontal force to ea
goblinko [34]

The gravitational force on block B is twice as much as the gravitational force on block A.

<h3>What is Force?</h3>

Force is the product of mass and acceleration. If the mass of A is 1Kg and the mass of B is 2Kg, In order to give the masses the same horizontal acceleration, the magnitude of the force on block B must be twice as much as the force on block A.

Given that the mass of A is 1Kg and the mass of B is 2Kg, the gravitational force on block B is twice as much as the gravitational force on block A.

If I hold block A with a mass of 1 kg in one hand and block B with a mass of 2 kg in the other  and release both from the same height above the ground at the same time, the two blocks hit the ground at the same time, because they both accelerate at the same rate while falling. The greater gravitational force on block B is compensated by its greater mass, giving it the same acceleration.

A person is pushing a book lying on a table. Identify the different forces that act on
BaLLatris [955]

Explanation:

There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.

The fission of uranium can result in many different fission fragments. O True O False
WITCHER [35]

Answer:

True

Explanation:

Nuclear fission is a radio active decay or a nuclear reaction in which a heavy nucleus breaks or splits into lighter fragments or nuclei of comparable sizes.

The fission of Uranium-235 by absorbing a neutron which turns it into excited Uranium-236 which further splits into lighter nuclei releasing 3 neutrons and gamma rays.

The fission of Uranium - 235 results in fission fragments of Krypton-92 and Barium-141.
