Explanation:

How much energy does it take to heat 1 kg of water?

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn't take much energy to change its temperature.

To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.

can u figure it out from there but if anything i think it is  C

Answer:

Explanation:

140m

Explanation:

The velocity must be broken down into x (horizontal) and y (vertical) components. We can use the y component to find how high the object gets. To find vertical velocity, vy, use vy=vosinθ.

vy=(75ms)sin45o=53ms

Next we find how long it takes to reach the top of its trajectory using vf=vo+at.

0ms=53ms+(−10ms2)t

t = 5.3s

Finally, find how high the object goes with d=vot+12at2.

d=(53ms)5.3s+12(−10ms2)(5.3s)2=140m

Explanation:

Spring tides generally occur twice a month—during new and full moons, when the Earth, Sun, and Moon line up in a row. In this arrangement, the gravities of the Sun and Moon work together and have the strongest pull on Earth. This produces the largest difference between high and low tide.

Spring Tides

During full moon or new moon phases, the gravitational forces of the Sun and Moon are maximized, producing very large ranges of tidal highs and lows called spring tides

Answer: the answer is D (convection)

Answer:

D.Convection

Explanation:

Answer:

Heat

Explanation:

Heat. The thermal energy that flows from one substance to another when the substances differ in temperature. Thermal equilibrium. The state in which no thermal energy transfer occurs because both substances are at the same temperature. Specific heat.

Heat is the thermal energy that flows from one substance to another when the substances differ in temperature.

Thermal energy is the term used to describe the energy present in a system that is responsible for setting its temperature.

Here,

The average kinetic energy of the particles in a material is measured by its temperature. The overall kinetic energy of the particles in a material is measured by thermal energy.

The temperature and thermal energy of a material increase with the particle velocity.

The amount of thermal energy that is transferred from one media or object to another, or from an energy source to a medium or object, is measured in terms of heat.

Radiation, conduction, and convection are the three mechanisms through which such energy can be transferred.

The heat energy may be transformed into other types of energy, such as mechanical, kinetic energy, etc.

Hence,

Heat is the thermal energy that flows from one substance to another when the substances differ in temperature.

Answer:

I think you mean what was the force applied on the cannonball, right? Well, that would be 75 N(newtons).

Explanation:

F = ma(force = mass x acceleration). Plus in the values it would be...

F = m(10.0 kg) x a(7.5 m/s^2), or 75 kg/s^2/75 N(newtons). Easy math.

In a stable ecosystem, the number of predators increases if the number of prey increases.

Predators are the species that are dependent upon prey for their foods. predators actually hunt the prey for their food.

predators are the species that depend upon other living species like deer fish goats etc for example lions depend upon deer, zebras, etc.

while the preys are the species who depend upon the plants for their food so if the number of preys will be higher then the number of the predators will also be higher.

Thus In a stable ecosystem, the number of predators increases if the number of prey increases.

Answer:

[tex]a=-3846.46\ m/s^2[/tex]

Explanation:

Given that,

Initial velocity of the ball, u = 22.2 m/s

Final velocity of the ball, v = -14.9184 m/s (minus sign shows opposite direction of motion)

Time for contact, t = 0.00965 s

We need to find the average acceleration of the ball when it is in contact with the ball. The acceleration of an object is equal change in velocity per unit time. So,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{-14.9184 -22.2 }{0.00965 }\\\\a=-3846.46\ m/s^2[/tex]

So, the acceleration of the ball is [tex]3846.46\ m/s^2[/tex] towards the opposite direction of motion.

Answer:

5ms^-2

Explanation:

F = 20N, m = 4.0kg, a = ?

Using the formula for Force

F = ma

Then making acceleration the subject of the formula

a = F/m

a = 20N/4.0kg

a = 5ms^-2

The formula for calculating the magnitude of the resultant vector is expressed as;

[tex]R = \sqrt{(\sum Fx)^2+(\sum Fy)^2}[/tex]

[tex]\sum Fx[/tex] is the sum of distances along the x component

[tex]\sum Fy[/tex]  is the sum of distances along the y component

[tex]\sum Fx = 45 cos 25^0\\\sum Fx = 40.78m\\\\\sum Fy = -45 sin 25^0+30\\\sum Fx = 10.98m\\[/tex]

[tex]R = \sqrt{(40.78)^2+(10.98)^2}\\R = \sqrt{1663.0084+(120.61)}\\R = \sqrt{(1783.6184}\\R = 42.23m[/tex]

Hence the magnitude of the resultant vector is 42.23m

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.
