By Newton's second law, the net force on the object is
∑ <em>F</em> = <em>m</em> <em>a</em>
∑ <em>F</em> = (2.00 kg) (8 <em>i</em> + 6 <em>j</em> ) m/s^2 = (16.0 <em>i</em> + 12.0 <em>j</em> ) N
Let <em>f</em> be the unknown force. Then
∑ <em>F</em> = (30.0 <em>i</em> + 16 <em>j</em> ) N + (-12.0 <em>i</em> + 8.0 <em>j</em> ) N + <em>f</em>
=> <em>f</em> = (-2.0 <em>i</em> - 12.0 <em>j</em> ) N
Answer:
apply a voltage to a cable a current is created that increases linearly with the voltage
Explanation:
apply a voltage to a cable a current is created that increases linearly with the voltage according to the ohm ratio
V = I R
Where R is the resistance of the wire
If the applied voltage is high, the amount of current is also high, which is why when there are many electrons displacing ce, the shock between them increases significantly, causing an increase in the temperature of the cable that is reflected in an increase in resistance, for which continue to comply with Ohm's law the current should be a little lower
Electrons have a negative charge. Protons have a positive charge. I am sorry I do not know the last question...
In Medicine, "etiology" means the origin or cause of a disease.
Similar to Hippocrates, modern scientists who study etiology believe that diseases come from natural causes such as bites from infected insects.
Explanation:
A ball is thrown straight upward and falls back to Earth. It means that it is coming to the initial position. Displacement is given by the difference of final position and initial position. The displacement of the ball will be 0. As a result velocity will be 0.
Acceleration is equal to the rate of change of velocity. So, its acceleration is also equal to 0.
Hence, displacement, velocity and acceleration are zero.
