Determine if each picture is a high or low tide.
Note: only ONE picture can be a high tide and only ONE picture can be a low tide!

Answer:

Correct option is (a)

Explanation:

According to conservation of energy: Total energy of system remains conserved or we can say total energy = constant

(a) 400J of GPE is added and 250J of thermal energy is lost

⇒ Total energy = 400-250 J  = 150 J

hence, 150J energy is increased

(b) 100J of thermal energy is added and 450J of kinetic energy is lost

⇒ Total energy = 100-450 J  = -350 J

hence, 350J energy is decreased or lost by system

(c)200J of kinetic energy is added and 250J of thermal energy is lost

⇒ Total energy = 200-250 J  = -50 J

hence, 50J energy is decreased or lost by system

(d)300J of thermal energy is added and 450J of kinetic energy is lost

⇒ Total energy = 300-450 J  = -150 J

hence, 150J energy is decreased or lost by system

Therefore, correct option is (a)

Answer:

Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity. For example, a puck sliding along a horizontal plane of ice after being hit with a hockey stick.

Explanation:

Answer:

The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Explanation:

please mark me as brainliest thank you

The number of complete wavelengths in a given  time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease.

The frequency referred to the  number of oscillation per unit time and it is used for defining the cyclic process like rotation, oscillation, wave etc.

The SI unit is denoted as Hertz and the symbol λ represents it where one hertz means the wave completed one cycle in one second.

The frequency explains the phenomenon of oscillatory and vibration like the mechanical vibration, sound signals, light, frequency waves etc. The  “period” represented as the time required by the wave for one oscillation, i.e., it is inversely proportional to the frequency.

Image result for During a spring tide, the high tides are very high and the low tides are very low. Why does this occur?

In both cases, the gravitational pull of the sun is 'added' to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are higher and low tides are lower than average. These are called 'spring tides. '

Answer:

4202.4 J

Explanation:

The formula for calculating the heat absorbed by ice to melt into water is given by :

ΔH = Cp × m × Δ T   -------where ;

Cp =specific heat of ice = 2.06 J/g° C

m= mass of ice = 102 g

ΔT = 0°C--20°C = 20°C

Thermal energy absorbed by the ice will be;

ΔH = Cp × m × Δ T  

ΔH = 2.06 * 102 * 20

ΔH =4202.4 J

Answer:

Vbag = 4.22 [m/s]

Explanation:

In order to solve this problem we must use the principle of conservation of momentum. Which tells us that the momentum of a system is preserved before and after a collision.

Let's take both movements (bag and cart) as positive, since they both move in the same direction. Now everything that happens before the collision will be taken to the left of the equation and after the collision to the right of the equal sign.

[tex](m_{bag}*v_{bag})=(m_{bag}+m_{cart})*v_{final}[/tex]

where:

mbag = mass of the bag = 22 [kg]

vbag = velocity of the bag [m/s]

mcart = mass of the cart = 9 [kg]

vfinal = mass of both bodies moving together = 3 [m/s]

Now replacing:

[tex](22*v_{bag})=(22+9)*3\\22*v_{bag}=93\\v_{bag}=4.22[m/s][/tex]

Answer:

The amount of heat energy that must be removed from the mixture to cool it to its freezing point, of -16°C is 45,360 J

Explanation:

The given parameters for the refrigeration unit and the ice cream are;

The power of the refrigeration unit = 120 J/s

The mass of the liquid ice cream, m = 0.6 kg

The initial temperature of the liquid ice cream, T₁ = 20°C

The freezing point temperature of the ice cream, T₂ = -16°C

The specific heat capacity of the ice cream, c = 2,100 J/kg⁻¹·°C⁻¹

The amount of heat energy that must be removed from the mixture to cool it to its freezing point, ΔQ, is given as follows;

ΔQ = m × c × ΔT

Where;

ΔT = T₁ - T₂

∴ ΔQ = m × c × (T₁ - T₂)

Therefore, by substituting the known values, we have;

ΔQ = 0.6 × 2,100 × (20 - (-16)) = 45,360

The amount of heat energy that must be removed from the mixture to cool it to its freezing point, of -16°C = ΔQ = 45,360 J.

Answer:

Answer: .164

Explanation:

1120x10^6 is the coefficient for ethyl alcohol b

(.00823)/(1120x10^-6)(44.8) which gives you your answer: 0.164 m^3

A vat of ethyl alcohol expands by 0.00823 m^3 when the temperature is raised by 44.8°C. The original volume of the alcohol is 0.164m³.

A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units. Volume and the notion of length are connected.

The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

A three-dimensional object's volume is the area it takes up, and it is expressed in cubic units. Cm3 and in3 are two examples of cubic units. The amount of matter in an item can be determined by its mass, on the other hand.

1120 x 10⁶ is the coefficient for ethyl alcohol b

= (.00823 ) / ( 1120 x 10⁻⁶) ( 44.8 )

= 0.164 m³

Thus, The original volume of the alcohol is 0.164m³.

Answer:

A earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves

Answer:

Transverse

Explanation:

Electromagnetic waves don't depend on the medium they travel through like a mechanical wave does, so they aren't mechanical. They don't oscillate (move back in forth) in the direction they travel either, ruling out compressional and longitudinal waves.

That leaves tranverse waves, the ones we're most used to, since they look very "wavelike," with smooth peaks and valleys. Electromagnic waves behave like these, oscillating in a plane perpendicular to the direction they're traveling in.

When two objects interact, they exert forces on each other. These forces act  in opposite directions.

According to Newton's third law of motion, every action has an equal and opposite reaction. As well as, the action and reaction are always acted in pairs.

When two things collide, they exert forces on one another. These forces have opposing effects.
