Just like elephants, gorillas and dolphins, wolves educate their young. True or False?

Answer:  19.6 watts

=================================================

Explanation:

power = (change in work)/(change in time)

p = w/t

work = force*displacement

w = f*d

So we can say:

p = (f*d)/t

We know the following

Leading to...

p = (f*d)/t

p = (49*2)/5

p = 98/5

p = 19.6 watts

Side note: 1 watt is equal to 1 joule per second

This may be the result of the material's own properties or its interactions with other substances. The U.S. Environmental Protection Agency (EPA), the U.S. Occupational Safety and Health Administration (OSHA), the U.S. Department of Transportation (DOT), and the U.S.

Nuclear Regulatory Commission are primarily responsible for defining and enforcing laws and regulations related to hazardous materials (NRC). Each defines "hazardous substance" differently.

This includes chemicals such as carcinogens, irritants, corrosives, toxic agents, sensitizers, agents that damage the lungs, skin, eyes, or mucous membranes; chemicals that can combust, explode, are flammable, oxidizers, pyrophorics, unstable-reactive or water-reactive.

Therefore, Any object or agent (biological, chemical, radiological, and/or physical) that has the potential to harm people, animals, or the environment is considered a hazardous material.

A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil up and down. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards. In this case, the particles of the medium move perpendicular to the direction that the pulse moves. This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion.

A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced leftwards and rightwards. In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.

Answer:

For instance, an immobile object located at some height above the ground has potential energy. If the object starts to fall, its potential energy is converted to motion or kinetic energy. The heavier and the higher the object is, the more potential energy it will have. Transfer of thermal energy via conduction is aided by vigorously vibrating particles in a medium that has gained energy through heating.

Explanation:

To make a quick stop, when a driver puts his or her feet on the brakes, at that moment, some of the motion energy gets modified to sound energy and thermal energy. This is one of the examples, when the motion energy of the object changes, resulting in some other change in energy as well.  

• The other term for motion energy is mechanical energy. It is the energy stored within the moving objects. When the object moves faster, more amount of energy storage takes place.  

• Motion energy is the sum of the kinetic and potential energy within an object, which is used to perform some kind of work.

Answer:

The body flies off to the left at 9.1 m/s

Explanation:

Law Of Conservation Of Linear Momentum

It states the total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and speed v is  

P=mv.  

If we have a system of bodies, then the total momentum is the sum of the individual momentums:

[tex]P=m_1v_1+m_2v_2+...+m_nv_n[/tex]

If a collision occurs and the velocities change to v', the final momentum is:

[tex]P'=m_1v'_1+m_2v'_2+...+m_nv'_n[/tex]

Since the total momentum is conserved, then:

P = P'

In a system of two masses, the equation simplifies to:

[tex]m_1v_1+m_2v_2=m_1v'_1+m_2v'_2\qquad\qquad[1][/tex]

Wall-E robot is initially at rest, its two parts together. His head has a mass of m1=0.75 kg and his body has a mass of m2=6.2 kg. Both parts have initial speeds of zero v1=v2=0.

After the explosion, his head flies off to the right at v1'=75 m/s. We are required to find the speed of his body v2'. Solving [1] for v2':

[tex]\displaystyle v'_2=\frac{m_1v_1+m_2v_2-m_1v'_1}{m_2}[/tex]

Substituting values:

[tex]\displaystyle v'_2=\frac{0.75*0+6.2*0-0.75*75}{6.2}[/tex]

[tex]\displaystyle v'_2=-9.1 \ m/s[/tex]

When a  person walks 60.0m and then walks 130m then the displacement of the person would be 70 meters if he first walked east and then west.

An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.

As given in the problem a person walks 60.0m and then walks 130m and if he first walks east then west then we have to find the displacement.

Displacement = final position -initial position

Lets us consider eastward as positive direction,

displacement = 60 - 130

                       = -70 meters

The negative sign represents the displacement would be in a westward direction.

Thus, If a guy initially went east and then west, his displacement would be 70 meters when he traveled 60.0 meters and then 130 meters.

Explanation:

Answer: C

Explanation:

Waves with a higher frequency have crests that are closer together, so higher frequency waves have shorter wavelengths.

Answer:

T_finalmix = 45 [°C].

Explanation:

In order to solve this problem, a thermal balance must be performed, where the heat is transferred from water with the highest temperature, to the water with the lowest temperature, so the final temperature of the mix must be equal once the thermal balance is achieved.

[tex]Q_{water}=Q_{methanol}[/tex]

where:

[tex]Q_{water}=m_{water}*Cp_{water}*(T_{waterinitial}-T_{final})[/tex]

mwater = mass of the water = 300 [g] = 0.3 [kg]

Cp_water = specific heat of the water = 4180 [J/kg*°C]

T_waterinitial = initial temperature of the water = 80 [°C]

T_finalmix = final temperature of the mix [°C]

[tex]Q_{water}=m_{water}*Cp_{water}*(T_{final}-T_{water})[/tex]

Now replacing:

[tex]0.3*4180*(80-T_{final})=0.3*4180*(T_{final}-10)\\100320-1254*T_{final}=1254*T_{final}-12540\\112860=2508*T_{final}\\T_{final}=45[C][/tex]

The final temperature of the mixture is 45 °C

Heat lost by warm water = Heat gained by cold water

Qᵥᵥ = Q꜀

MᵥᵥC(Tᵥᵥ – Tₑ) = M꜀C(Tₑ – T꜀)

0.3 × 4180 × (80 – Tₑ) = 0.3 × 4180 × (Tₑ – 10)

1254 (80 – Tₑ) = 1254(Tₑ – 10)

Clear bracket

100320 – 1254Tₑ = 1254Tₑ – 12540

Collect like terms

100320 + 12540 = 1254Tₑ + 1254Tₑ

112860 = 2508Tₑ

Divide both side by 2508

Tₑ = 112860 / 2508

Tₑ = 45 °C

Thus, the final temperature of the mixture is 45 °C
