A flask with a tap has a volume of 200cm3 when full of air, tye flask has a mass of 30.98g. the flask is connected to vacuum pump, the air is pimped put and then the tap is closed, the flask now has mass of 30.72gcalculate:
a. the mass of air in the flask before connecting to vacuum pump, in g
b. the density of the air in the flask

Answers

Answer 1

Answer:

(a) The mass of air in the flask before connecting to vacuum pump is 30.98 g

(b) The density of the air in the flask is 0.155 g/cm³

The given parameter:

volume of the flask, V = 200 cm³

the initial mass of the flask, m = 30.98 g

final mass of the flask = 30.72 g

To find:

a. the mass of air in the flask before connecting to vacuum pump, in g

b. the density of the air in the flask

The mass of air in the flask before connecting to vacuum pump is 30.98 g

The density of the air in the flask is calculated as:

$density = (mass)/(volume) = (30.98 \ g)/(200 \ cm^3) = 0.155 \ g/cm^3$

What force is needed to give a 0.25-kg arrow an acceleration of 196 m/s2? A. 0.25 N B. 49 N C. 196 N D. 748 N

Answers

The answer is B. 49 N

Force is equal to the mass of that object multiplied by itsacceleration:

F = m × a
The unit of force is N = kg * m/s².

It is given:
m = 0.25 kg
a = 196 m/s²

F = m × a = 0.25 kg × 196 m/s² = 49 N

B.49 N is the ANSWER! I took the test on k12 and it was right

sticking your fingers into a wall socket will not bring you into direct contact with an electrical current. true or false

Answers

Answer:

False

Explanation: Sticking fingers into a wall socket will bring us into direct contact with an electrical current because human body is a conductor of electricity. Effect of electric current is visible when circuit of flow is complete. In this case when we touch live wire or socket human body complete its circuit and get an electric shock. Sometimes this can be avoided by wearing footwear made up of insulator.

the correct answer is false cause how can u fit your finger in a wall something it's to small
