How is total force calculated?
We can figure out the total force by subtracting one force from the other. For example, if a block is being pushed with a force of 7 newtons left and 4 newtons right, the total force on the block is 3 newtons left.
Is swimming a push or pull force?
Take your hand and draw it through water in a pool. You can feel resistance—this is hydrodynamic drag. It is the effective force created by the interaction of your body and the water. Swimmers push against water to move forward, and water pushes back to slow them down.
What is the fastest stroke?
freestyle
Which stroke is the only style in which swimmers are face up in the water?
backstroke
What forces slow you down when swimming?
Friction in Swimming: When you are swimming you are almost always at battle with friction. Friction is part of the drag that catches on to you when you are swimming. As well as friction is the water resistance that is trying to slow you down when you are swimming.
What are the 4 fundamental forces in order of strength?
Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
What is the most powerful source on earth?
Nuclear Has The Highest Capacity Factor This basically means nuclear power plants are producing maximum power more than 93% of the time during the year. That’s about 1.5 to 2 times more as natural gas and coal units, and 2.5 to 3.5 times more reliable than wind and solar plants.
What is the most powerful thing in the human body?
The brain
What is the strongest natural element?
tungsten
What is the safest form of power?
Nuclear energy, for example, results in 99.8% fewer deaths than brown coal; 99.7% fewer than coal; 99.6% fewer than oil; and 97.5% fewer than gas. Wind, solar and hydropower are more safe yet.
Which country has the cleanest energy?
Germany
Which country has most expensive electricity?
Which country uses most solar energy?
China
Is Germany 100 solar powered?
Germany has promised to transform its electricity supply to 100 percent renewable energy by 2050. Germany has pledged to reduce greenhouse gas emissions by 40% below 1990 levels by 2020 and by 80-85 percent by 2050 from 1990 levels.
Which is the biggest solar plant in the world?
Bhadla Solar Park
Which country is first in solar energy?
By early 2020, the leading country for solar power was China with 208 GW, accounting for one-third of global installed solar capacity. As of 2020, there are at least 37 countries around the world with a cumulative PV capacity of more than one gigawatt.
