Answer:
<h2>6.67 m/s²</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
m is the mass
From the question we have
We have the final answer as
<h3>6.67 m/s²</h3>Hope this helps you
is the equation that represents the Joule's law of heating.
Joule's law of heating defines the heat generated by any current flowing conductor is directly proportional to
1. Square of Current (I²),
2. Resistance of the conductor (R)
3. Time for which current is passed (t)
Hence, Heat generated = .....................(1)
By Ohm's Law, the potential difference (V) across a conductor is directly proportional to the current(I) flowing through it. The constant of proportionality is termed as resistance of the conductor (R).
...............................................(2)
From (2), Current (I) can be rewritten as
........................................................(3)
Substituting (3) in (1), we get
Answer:
a) Volume = 2/3 r³
Volume = 2/3 × 22/7 × 14 × 14 × 14 = 5749.3 cm³
b) Total surface area = 3r²
Area = 3 × 22/7 × 14 × 14 = 1848 cm²
