The battery is made up of three 1.5 V cells.
Calculate the total potential difference of the battery.

Answer:

30 maybe?

Explanation:

Answer:- 30 km/hr

Given :- Distance covered by Salesman 50 km

Time taken;- 2 hrs and 30 minutes

Speed of salesman: Distance/ time taken

50 / 2 1/2 = 20 km/hr

He has make it 5/6 less

2 1/2 —5 / 6 = 5 / 3 hrs

Speed : Distance / Time

50 km / 5/3 = 30

He has to travel at 30 km per hour.

P = 2,000 W

Explanation:

Work and Power

Work is the amount of energy transferred by a force over a distance. It's a scalar quantity, with SI units of joules.

If both the force F and displacement s are parallel, then we can use the equivalent scalar formula:

W=F.s

Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.

The power can be calculated as:

[tex]\displaystyle P=\frac {W}{t}[/tex]

Where W is the work and t is the time.

A box with a weight of 1,000N is lifted by s=20 m by a rope and pulley system. The system exerts a force equal to the weight of the box, thus F=1,000 N. The work done by the system is:

W =1,000 N * 20 m

W = 20,000 J

Now we calculate the power developed by the system in t=10 seconds:

[tex]\displaystyle P=\frac {20,000}{10}[/tex]

P = 2,000 W

During the formation of the aurora borealis, the electrons in an atom experience a change in energy levels. Which statement about this change is accurate?

First, the electron absorbs energy to move to a higher energy level.

The energy transferred from an electron in the solar wind is equals to energy absorbed by an electron in the oxygen atom.

Energy transformation is the process of changing energy from one form to another form.

It is known that  the energy transferred from an electron in the solar wind is equals to energy absorbed by an electron in the oxygen atom.

Hence the energy transferred from an electron in the solar wind is equals to energy absorbed by an electron in the oxygen atom.

Answer:

The second box

Explanation:

Work done is the force applied to move a body through a particular distance.

Work done  = Force x distance

For the first box:

Weight  = 12N

Distance  = 1m

  Work done  = 12 x 1 = 12J

For the second box;

 Weight  = 1000N

 Distance  = 30cm  = 0.3m

 Work done  = 1000 x 0.3  = 300J

The second box has a higher work done.

Answer:

A. 2000 m/s

Explanation:

Answer:

4 J

Explanation:

From the image attached, we can see 2 horizontal forces acting on the box albeit in opposite directions.

Now, the net force will be;

F_net = 3 - 1

F_net = 2 N

To move a distance of 2 metres, kinetic energy is;

K.E = Force × Distance = 2 × 2 = 4 J

The main cause of weather is differences in temperature around the Earth.

The weather could define the atmosphere. It could be either hot, cold, cloudy, or stormy. In the case of the earth, the phenomena of weather should arise at the bottom layer of the planet's atmosphere. Due to this, the main cause of the weather should be of differences.

Answer:

there is the answer

Explanation:

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Answer:

Yes

Explanation:

It is possible for sedimentary rocks to be converted to igneous rocks. Under conditions of high temperature and pressure, sedimentary rocks can be broken down into igneous rock by melting this rock type.

When the rock is broken down, it forms melt which when cooled and solidifies will form igneous rocks.

Sedimentary rocks are formed from the breaking down of pre-existing rocks through the action of weathering, erosion and sediment transportation. Within a basin, the sediments are compacted and lithified.

When this is subjected to intense pressure and temperature, the rock hardens and might further break down to melt.

Newton’s Law of Universal Gravitation

It states that objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance between them.  The formula is:

[tex]\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]

Where:

m1 = mass of object 1

m2 = mass of object 2

r     = distance between the objects' center of masses

G   = gravitational constant: [tex]6.67\cdot 10^{-11}~Nw*m^2/Kg^2[/tex]

The center of mass of a cow is at a distance of r=208 m from the center of the mass of a tractor. The gravitational force of attraction is [tex]F=1.8\cdot 10^{-9}\ N[/tex]. It's required to find the new force of attraction F' if the distance was r'=416 m.

It can be noted that r'=2r. If the distance is doubled, the new force is:

[tex]\displaystyle F'=G{\frac {m_{1}m_{2}}{(2r)^{2}}}[/tex]

[tex]\displaystyle F'=\frac{1}{4}G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]

Substituting the original value of F:

[tex]\displaystyle F'=\frac{1}{4}\cdot 1.8\cdot 10^{-9}\ N[/tex]

Operating:

[tex]\displaystyle F'=4.5\cdot 10^{-10}\ N[/tex]

Choice: D.
