The answer is option D.
Area of sheet, A1 = length × breadth
= (8.5 inch * 2.54 cm) ×11 inch * 2.54 cm)
= 603.22
Now, Mass of sheet, M1 = 4.50 gms
Thus, Area of sheet A2, = 1
And, Mass of sheet, M2 = ?
Thus, Mass of M2 =
= 0.0073
To find the answer, take 55 and divide it by 1.85 to get the thickness of one card. In this case the answer would be 29.72973 cm. each.
Answer:
Yes . Frictions was not included for the calculation for acceleration .
Explanation:
This is because we're considering the weight of an object which isn't acceleration i:e frictionless.
If friction is included, the equation for acceleration becomes.
F= ma,(Newton second law of motion)
where F=frictional force , m =mass of the object and a=acceleration..
So therefore, a = F/m.
2 minutes is 120 seconds, so if you were finding vibrations per minute, it would be 60 times a minute.
