Explanation:

Answer:

110.4 v

Explanation:

Find the equivalent resistance of the two parallel circuits

R1 and R2 in parallel   =   R1 * R2 / (R1+ R2) =   1 ohm

 similarly R4 and R5 =  4.77 ohms

Now you can add the three resistances into one  (R3=10)

    1 ohm + 10 ohm + 4.77 ohm = 15.77 ohms

Now

V = IR

V =  7 amps  * 15.77 ohm = 110.4 v

Option D is correct. P wave can travel through liquids. P stand for the primary of pressure wave.

A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify it. Transverse and longitudinal are the two main forms.

P waves are sometimes known as primary waves or pressure waves. The earliest waves of an earthquake are known as P waves.

P waves may pass through any medium, including liquids, gases, and solids. P waves can't move particles up and down or side to side.

P wave can travel through liquids. P stand for the primary of pressure wave.

Hence, option D is correct

Answer:

See below

Explanation:

At point A    the PE = mgh = 2 * 10 * 1 = 20 J

  at point B, all of the PE , 20 J , is converted to Kinetic Energy

KE = 1/2 m v^2

20 = 1/2 (2)(v^2 )

20 = v^2     v = sqrt 20 = 4.47 m/s

for the friction part

 vf = vo t  + 1/2 a t^2      vf = final velocity = 0 (stopped)

                                       vo = original velocity = 4.47 m/s  

                                         a = -1 m/s^2

  0 = 4.47 t + 1/2 (-1) t^2

            - .5t^2  + 4.47 t = 0

                 t ( -.5t+ 4.47) = 0    shows t =  4.47/.5 = 8.9 seconds

Forming an hypothesis is the first step in the scientific method.

A hypothesis can be defined as a guess as to what will happen during your experiment. Hypothesis can in other terms be defined as a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories.

As a result, light travels fastest in empty space, and travels slowest in solids. In glass, for example, light travels about 197,000 km/s.

Explanation:

The final velocity of m₁=2kg with its velocity at 5m/s will be 4 m/s.

According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.

The given data in the problem is;

(m₁) is the mass = 2 kg

initial velocity (u₁) =5m/s

(m₂) is the mass  = 0.5

(u₂) initial velocity = 0 m/s

(v) is the velocity  =.?

According to the law of conservation of momentum;

Momentum before collision =Momentum after collision

[tex]\rm m_1u_1 + m_2u_2 = v(m_1 + m_2) \\\\ 2(5) + 0.5(0) = v(2 + 0.5)\\\\10 = 2.5v\\\\ v = \frac{10}{2.5} \\\\ v = 4 \ m/s[/tex]

Hence,The final velocity of m₁=2kg with its velocity at 5m/s will be 4 m/s.

We can confirm that a contact force would be one in which physical contact is needed, while a no contact force does not require contact.

There are many everyday examples to be used to describe each of these forces. A very common no contact force is gravity. The Earth's gravity exerts a force on all things near the planet, but it does not need to be in physical contact to exert this force, thus making gravity a no contact force. An example of a contact force would be if you were to push another person. You are exerting a force that requires physical contact.

Therefore, we can confirm that a contact force would be one in which physical contact is needed, while a no contact force does not require contact.
