Answer:

circular motion

Explanation:

Circular motion can be regarded as

movement of particular object along the circumference in a circle. It is

rotation of particular object along a circular path. Circular motion could be

uniform, along with constant angular rate of rotation as well as constant speed. It could also be non-uniform along with changing rate of rotation. The acceleration that is been experienced when one is in uniform circular motion is called"Centripetal acceleration"

Convection currents is type of current that takes place after a reservoir of fluid has been heated at the bottom, then cool at the top.the fluid expand as a result of Heat , then density decreases, the plates on top of them is been carried as a result of circular motion of the convection

A convention current is a circular movement which is set up due to temperature difference between two layers of a fluid.

A convention current is a movement which is set up due to temperature difference between two fluids.

Convection currents are set up in liquids and gases.

Hotter and less dense fluids move upwards while colder and denser fluids move downwards.

Therefore, convection currents involve circular motion.

Answer:

15129.8 Kg•m/s

Explanation:

From the question given above, the following data were obtained:

Mass = 2020 kg

Velocity = 7.49 m/s

Momentum =?

Momentum is simply defined as the product of mass and velocity. Mathematically, it is expressed as:

Momentum = mass × velocity

With the above formula, we can obtain the momentum of the Elephant as follow:

Mass = 2020 kg

Velocity = 7.49 m/s

Momentum =?

Momentum = mass × velocity

Momentum = 2020 × 7.49

Momentum = 15129.8 Kg•m/s

Thus, the momentum of the Elephant is 15129.8 Kg•m/s

t = usin©/g

Where t is the time to reach the maximum height

Time spent in air is T = 2t

Hence, T = 2usin©/g

T = 2 x 20 x sin 65°/ 9.8

Explanation:

Given that,

The mass of a truck, m = 200 kg

Speed of the truck, v = 20 m/s

We need to find the momentum of the truck. The formula for momentum is given by :

p = mv

so,

[tex]p=200\times 20\\\\p=4000\ kg-m/s[/tex]

So, the momentum of the truck is equal to 4000 kg-m/s.

A roller coaster has a mass of 250 kg, and it is 50 meters above the ground, then the potential energy will be equal to 122.5 KJ.

Potential energy is a type of energy stored that depends on the interaction between various substances. A spring's energy rises when it is crushed or expanded. A steel ball has more energy stored if it is lifted just above the floor as contrasted to dropping to the ground. As raised, it can do greater labor.

Instead of being a property of specific entities or atoms, potential energy is a property of systems. For instance, a system made up of Earth and the raised ball has far more stored energy as they move apart.

In system components, where the configurations, or spatial arrangements, dictate the magnitude of the forces that apply against one another, potential energy arises.

From the data given in the question,

Mass, m = 250 kg

Height, h = 50 meters and,

g = 9.8 m/s²

[tex]Potential energy(PE)=mgh[/tex]

PE = 250 × 50 × 9.8

PE = 122500 J or,

PE = 122.5 KJ.

Answer:

9.6 Amperes

Explanation:

1/R = 1 /5 + 1/5 + 1/5 + 1/5

solving for R we get 5/4 ohms

then from V=IR

I = V/R

I=12/(5/4)

hence I= 9.6 Amperes

A 12.0-volt battery is connected in a series, then the current through the battery is 9.6 A.

Electrical resistance is implemented as a circuit element by resistors, which are passive two-terminal electrical components. Resistors are devices that are used in electronic circuits for a variety of purposes, including lowering current flow, adjusting signal levels, dividing voltages, biasing active components, and terminating transmission lines.

As part of motor controllers, power distribution systems, or as test loads for generators, high-power resistors that can dissipate many watts of electrical energy as heat may be used.

According to the question,

1/R = 1 /5 + 1/5 + 1/5 + 1/5

R = 5/4 ohms

By ohm's law,

V=IR

I = V/R

I=12/(5/4)

I= 9.6 Amperes

Explanation:

Given that,

A sphere is released into the atmosphere where air resistance is present.

The lose in energy is equal to 7 J

We need to find the gain in its kinetic energy.

We know that, as per the law of conservation of energy,

Loss in potential energy = gain in kinetic energy

⇒

Gain in kinetic energy = 7 J

Hence, the gain in kinetic energy is 7 J.

Answer:

a)   F = 15.6 10⁻¹⁹  k^   N,  b)  F = -1  10⁻¹⁹  k^   N,

c)  F = (8.3 i^ + 73 k^) 10⁻¹⁹ N

Explanation:

In this exercise we calculate the magnetic and electric force separately.

Let's start by calculating the magnetic force

       F_m = q v x B

where bold letters indicate vectors, the modulus of this expression is

       F_m = q v B

the direction is given by the right hand rule, where the thumb points in the direction of velocity, the fingers are extended in the direction of the magnetic field and the palm is in the directional ne force if the charge is positive

let's calculate the magnitude

      F_m = 1.6 10⁻¹⁹  1840  2.48 10⁻³

      F_m = 7.3 10⁻¹⁹ N

we calculate the direction, the thumb is in the direction of + y,

fingers extended in the direction of -ax

the palm remains + z

therefore the magnetic force is in the direction of the positive side of the z axis

The electric force is

        F_e = q E

give several possibilities for the electric field

a) electric field E = 5.19 V / m in the direction of + z

we calculate

        F_e = 1.6 10⁻¹⁹ 5.19

        F_e = 8.3 10⁻¹⁹ N

the total force is

       F = F_m + F_e

       F = (8.3 k ^ + 7.3 k ^) 10⁻¹⁹

       F = 15.6 10⁻¹⁹  k^   N

b) in the -z direction

       F_e = -8.3 10⁻¹⁹ k^   N

       F = Fm + Fe

       F = (-8.3 k ^ + 7.3 k ^) 10⁻¹⁹

       F = -1  10⁻¹⁹  k^   N

c) in the + x direction

       F_e = 8.3 10⁻¹⁹  i^   N

the total force is

       F = (8.3 i^ + 73 k^) 10⁻¹⁹ N
