The forces are the same like the third law of Newton states.I think
Answer:
60 ohms
Explanation:
From Ohm's Law:
V = IR
Where V = 120volts
I = 2A
R = ?
Note that R,V and I represents resistance, voltage and current respectively.
Substituting the above values into the formula.
V = IR
120v = 2×R
120= 2R
Making R the subject
R =120/2
R = 60 ohms
Hence the resistance of the toaster will be 60 ohms.
Answer:
E = 0.1472 J
Explanation:
Given that,
The number of turns in the solenoid, N = 2100
Area of the solenoid, A = 10 cm² = 0.001 m²
The length of the solenoid, l = 30 cm = 0.3 m
Current in the solenoid, I = 4 A
We need to find the magnetic energy stored in the solenoid. The expression for the stored energy is :
Where
L is self inductance of the solenoid,
So,
So, 0.1472 J of energy is stored in the solenoid.
Answer : Option C) copy the movements performed during the activity.
Explanation : Arm circles are an effective dynamic stretch for swimmers because they copy the movements performed during the activity.
During swimming when the arm circles are performed it stretches the triceps brachii, loosens the shoulder blade and stretches the side muscles.
Often many people are observed to perform this arm circles stretch without bringing the elbow behind the head, but especially for swimmers, this increases the stretching length and reduces stress while swimming.
Answer:
Pressure increases as you move deeper below earth's surface.
Tempurature increases as you move deeper below earth's surface.
