Four discs are spinning at constant angular velocity. Four ideantical balls are dropped on the discs at different distances from

Arlecino [84]

Answer: They will have equal final angular velocity.

Explanation:

Since the discs starts from rest and rotates about a ﬁxed axis, they are subject to a constant net torque. The work done by the torque during the second revolution is as the work done during the ﬁrst revolution.

The four disc will turn through equal angles in equal times.

d. e. Study the given diagram and calculate the following: i. work done by load ii. work done by effort iii. M.A iv. V.R v. effi

il63 [147K]

i. The work done by the load is load x distance moved by load.

ii. The work done by effort is effort applied x distance moved by effort.

iii. The mechanical advantage of the simple machine is Load/effort.

iv. The velocity ratio of the simple machine is 2.

v. The efficiency of the machine is M.A/V.R x 100%.

The work done by the load is the product of the load and the distance through which the load is moved. The magnitude is calculated as follows;

Work done by the load = load x distance moved by load

<h3>Work done by effort</h3>

The work done by the effort is the product of the effort and the distance through which the effort is applied. The magnitude is calculated as follows;

Work done by effort = effort applied x distance moved by effort

<h3>Mechanical advantage of the simple machine</h3>

M.A = Load/Effort

<h3>Velocity ratio of the simple machine</h3>

V.R = distance moved by effort / distance moved by load

V.R = 30 cm/15 cm

V.R = 2

<h3>Efficiency of the machine</h3>

E = (M.A/V.R) x 100%

Thus, the work done by the load is load x distance moved by load.

The work done by effort is effort applied x distance moved by effort.

The mechanical advantage of the simple machine is Load/effort.

The velocity ratio of the simple machine is 2.

The efficiency of the machine is M.A/V.R x 100%.

Which of the following must be the same before and after a chemical reaction?

madam [21]

Answer: Option (D) is the correct answer.

Explanation:

A chemical reaction is defined as the reaction which causes change in chemical composition of a substance.

According to law of conservation of mass, mass can neither be created nor it can be destroyed. It can only be changed from one form to another.

For example, $H^{+} + Cl^{-} \rightarrow HCl$

Here, total mass of reactants = (1.008 + 35.453) g/mol = 36.461 g/mol

Whereas total mass of products = 36.461 g/mol

This shows that mass remains the same before or after the reaction.

Similarly, the number of atoms of the type involved will remains the same as no change in their nucleus is occurring.

Thus, we can conclude that the following must be the same before and after a chemical reaction.

The sum of the masses of all substances involved.

The number of atoms of the type involved.
