The answer is A. Increase

The formula is <span>Voltage = Resistance X Current

Lets say the voltage is 10 and the resistence is 5

10 = 5 x current
Current = 2

Now, lets decrease the resistence from 5 to 2

10 = 2 x Current
Current = 5

The current increases

Nitella [24]

Individuals suffering from somatoform disorders often see several doctors about their symptoms because doctors often refer their patients for a second opinion

<h3>What is doctors opinion?</h3>

Doctors usually ask people to take different medications to be able to treat the cause and the symptoms of a disease.

For example, they might prescribe antibiotics to treat the infection and  anti-inflammatory medication for the swelling and pain.

According to this, the statement that says that doctors often advise a combination of treatments to eradicate an infection and treat symptoms is true.

Hence Individuals suffering from somatoform disorders often see several doctors about their symptoms because doctors often refer their patients for a second opinion

A 1400 kg compact car rear-ends a 2000 kg truck. which vehicle experiences the larger momentum change from the collision?
Fittoniya [83]

Both vehicles experience the same change in momentum.

When the compact car rear ends a truck, they exert equal forces on each other, in accordance with Newton's third law. The force exerted by the car on the truck is equal to the force exerted by the truck on the car.The force acting on the two bodies act for the same interval of time.

According to Newton's second law, the force acting on a body is equal to the rate of change of momentum.

Since the forces are equal,

F=\frac{\Delta p_1}{t} =\frac{\Delta p_2}{t}

therefore, the change in momentum of the car \Delta p_1is equal to the change in the momentum of the truck \Delta p_2.

Thus, both the car and the truck experience the same change in their momentum. However due to the smaller mass of the car, the change in its velocity is greater than the change in the truck's velocity, which has a larger mass.

Suppose you swing a ball of mass (m) in a vertical circle on a string of length (L). As you probably know from experience, there
KATRIN_1 [288]

Answer:

a)\omega =\sqrt{\dfrac{g}{L}}

b)N= 21.29 rpm

Explanation:

   Given that

Mass of the ball =m

Length of string = L

Lets take angular speed = ω

The centripetal force on the ball

F = m ω² L

To complete the circle ,at the top condition the force due to gravity should be equal to the centripetal force

Gravity force = mg

F= mg

m ω² L = m g

ω² L =  g

\omega =\sqrt{\dfrac{g}{L}}

When L= 2 m  

Lets take g =10 m/s²

\omega =\sqrt{\dfrac{g}{L}}

\omega =\sqrt{\dfrac{10}{2}}

ω = 2.23 rad/s

To convert in rpm

\omega =\dfrac{2\pi N}{60}

N=Speed in rpm

2.23 =\dfrac{2\pi N}{60}

N= 21.29 rpm

Investigators are working on a case where they need to know whether a watch will stop when it is dropped. In order to have a ver
ivanzaharov [21]

In order to have a verified or reliable answer to this question, they should take the watch apart and test the mechanism to see what causes failure.

Answer: Option D

<u>Explanation: </u>

For dropping a similar watch to record results, we need to buy another one. So, it becomes expensive. And, calling the manufacturer will give accurate results, but no knowledge. It is like getting multiple choices by luck.

Consulting senior faculty won’t result in any progress, because they may not have conducted these. So, one should rip off the watch, and study the mechanism, and its limitations.  The testing of mechanism gives the actual results.
