Answer:
3.88kg
Explanation:
From the question given, we obtained the following data:
W = 32N
g = 8.25 m/s2
M =?
W = M x g
M = W/g
M = 32/8.25
M = 3.88Kg
The mass of the object is 3.88kg
Answer:
If F is a constant, we can take f = 1
f = m×a
ma = 1
therefore we can say that force is hence proportinal to the product of mass and acceleration.
We know the formula for density = Mass/ volume
So Mass, M = Volume * Density
Volume = 3.5 L= 0.0035
Density = 1.50 g/ml = 1500 
Mass, M = 0.0035*1500 = 5.25 kg
So mass of liquid having density 1.50 g/ml and volume 3.5 liters is 5.25 kg.
To solve this problem we apply the concepts related to the electric torque generated by the electromagnetic field. Mathematically this Torque can be written under the following relation

Here,
N = Number of Turns
I = Current
A = Area
B = Magnetic Field
The maximum torque will be reached when the angle is 90 degrees, then we will have the following relation,

Magnetic Field is given at function of the number of loops, permeability constant at free space at the perimeter, then



Replacing at the first equation we have,
