Explanation:
H= mass× specific heat capacity×change in temperature
=2×380×(10-0)
=2×380×10
=7600Joules
Answer:
(a) 11.8692 ohm
(b) 12.447 A
(c) 17.6 A
Explanation:
a) inductive reactance Z = L Ω
= L x 2π x F
= 45.0 x 10⁻³ x 2(3.14) x 42
= 11.8692 ohm
b) rms current
= 100 / 8.034
= 12.447 A
c) maximum current in the circuit
= I eff x rac2
= 12.447 x 1.414
= 17.6 A
False<span>, well designed weight training programs actually target most of the muscles in the body. A good weight training program includes many compound exercises to activate multiple muscle groups and promote muscle hypertrophy. Some isolation exercises may also be included to target a specific muscle and help it grow.</span>

Answer:
Sedimentary rock is a rock formed underground, usually under a source of water too. The rock is made up of smaller rock that, over the years, fused together and solidified.
Answer:
Explanation:
1. All screws give the same M.A.
False - it depends on screw size and threads
2. A screw does its job by moving.
True - as far as screw as a machine
3. A screw with more threads has a smaller M.A.
False - more threads increase output force i.e. higher MA
4. Screws can be used to move things. *
True
