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:

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

Answer:

Explanation:

According to Newton's law of gravitation , all objects should take same time to fall from same height , but it does not happen when we see a paper , a thermocol and a plastic paper to fall .

It happens due to air resistance . In case of paper , this is most pronounced , so it falls slowest . In case of plastic paper , the resistance is least so it falls fastest .

If we squeeze the piece of paper to make a lump so that it does not remain flat , it will fall the fastest , because in this case the air resistance on it becomes the least .

Answer:it will take 10 hours

Explanation: The way we get this answer is if the boat travels 200 miles at 20 mph that means that every 20 miles the boat traveled an hour would pass. Using this we can see that 20 fits into 200, 10 times, meaning that the time it would take to travel would be 10 hours.

The time it will take to travel 200 miles is 10 seconds

The calculation can be done as follows

= 200/20

= 10 seconds

Hence the amount of time it will take the speed boat to travel 200 miles is 10 seconds

Explanation:

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

Force (F) = 50 N

Weight (W) = 100 N

Coefficient of static friction (μ) =.?

The coefficients of static friction (μ) is simply defined as the ratio of force (F) to the normal reaction (N). Mathematically, it can be expressed as:

μ = F / N

With the above formula, we can obtain the coefficient of static friction as follow:

Force (F) = 50 N

Weight (W) = 100 N

Coefficient of static friction (μ) =.?

μ = F / W

μ = 50 / 100

μ = 0.5

Thus, coefficient of static friction is 0.5

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.

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:

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.
