At 1:00 a.m., someone breaks a window in the back of a store and robs the safe. On the way out, the thief is cut on a piece of b

roken glass. A forensic team collects and tests a sample of blood left behind by the thief. It is O–. The police bring in a suspect with a cut forearm who was arrested just three blocks from the store. The person resembles someone seen leaving the store at the time of the robbery. A sample of the suspect’s blood is taken and tested for blood type. Once the suspect’s blood is mixed with anti-A serum, it is immediately clear that the suspect is not the person who was cut on the broken glass in the store. How did the test indicate that fact?

Describe how unbalanced & balanced forces are different and how this impacts on motion.
andrew-mc [135]
Balanced Forces are different from Unbalanced Forces because Balanced Forces are two forces acting in opposite directions of an object, and equal in size.On the other hand unbalanced forces are forces that cause a change in the motion of an object.

This impacts motion because when balance forces enter,... the object either stops (Stays at rest or moves at the same speed and direction) Unbalanced Forces causes an object to move faster/slower (might change the direction),.. due to one side having more force than the other.

stealth61 [152]

Answer:

On a brushed style generator, the increase in AC voltage from the slip rings is fed to the automatic voltage regulator, converted to DC voltage and fed into the rotor.

Explanation:

In an AC electrical generator, in order to maintain a fixed output, the output voltage  is taken from the slip rings to the brushes (some generators don't have brushes) and converted to DC voltage (since it is an AC generator) and fed back to the rotor.

The rotor winding rotate inside a stationary magnetic field known as stater which induces electrical current in the winding. These winding are connected to slip rings which transfers the current to the outside circuit.

I’m like kinda bad at physics so ya please help
uysha [10]

Answer:

99 joules.

Explanation:

Let m denotes mass of the object and v denotes velocity.

If mass has units of kilograms and the velocity has units of meters per second then the kinetic energy has units of joules.

Kinetic energy is an energy possessed by a body in motion.

Mass (m) = 99 kg

Velocity (v) = 2 m/s

To find kinetic energy, use the following formula:

Kinetic energy = \frac{1}{2}mv^2=\frac{1}{2}(99)(2)=99 joules
