Marianna [84]

There is a constriction made in a clinical thermometers.
As constriction stops the mercury inside the thermometer to drop back towards the bulb of thermometer.
So there is constriction used in clinical thermometers to prevent usage of alcohol or mercury into bulb

Two objects attract each other with a gravitational force of magnitude 9.20×10^-9 N when separated by 19.2 cm. If the total mass

melamori03 [73]

The gravitational force between two objects may be calculated by the equation,
F = G x (m1 x m2) / d²
where G is universal gravitational constant, m1 and m2 are the masses of two bodies and d is the distance between them. Substituting the known values,
9.20 x 10^-9 = (6.673 x 10^-11) (5.01 kg x m2) / (0.192m)²
The value of m2 is approximately 1.01 kg.

A 0.2 kg hockey puck moving at 80 m/s is caught by a 40 kg goalie at rest. With what speed does the goalie slide on the slide?

Lady_Fox [76]

Answer:

V = 0.39 m/s

Explanation:

Given that,

Mass of hockey puck, m = 0.2 kg

Mass of goalie = 40 kg

Speed of hockey puck, v = 80 m/s

We need to find the speed with which the goalie slide on the slide. Let V be the speed. Using the conservation of momentum as follows :

$mv=(M+m)V\\\\V=\dfrac{mv}{M+m}\\\\V=\dfrac{0.2\times 80}{0.2+40}\\\\V=0.39\ m/s$

So, the required speed is 0.39 m/s.
