Answer:
<h2>10.52 kg</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>10.52 kg</h3>
Hope this helps you
1.25m/s'2 by the first eq of motion

Answer:
44 ohm, 145 ohm
Explanation:
R = 44 ohm, L = 2.2 mH = 2.2 x 10^-3 H
At f = 60 Hz
XL = 2 π f L = 2 x 3.14 x 60 x 2.2 x 10^-3 = 0.82896 ohm
Impedance,
Z = 44 ohm
At f = 10 kHz = 10000 Hz
XL = 2 π f L = 2 x 3.14 x 10000 x 2.2 x 10^-3 = 138.16 ohm
Impedance,
Z =1 45 ohm
To solve this problem it is necessary to apply the concepts related to the Period based on the length of its rope and gravity, mathematically it can be expressed as
g = Gravity
L = Length
T = Period
Re-arrange to find the gravity we have
Our values are given as
Replacing we have
Therefore the correct answer is C.
Answer:
120 kg m/s
Explanation:
The magnitude of the momentum of an object is given by
where
m is the mass of the object
v is its speed
For the block in this problem,
m = 10.0 kg (mass of the block)
v = 12.0 m/s (speed of the block)
Therefore the magnitude of the block's momentum is
