1 answer:

8 0

I believe this question should be in Health, however, I'll answer it to the best of my ability.

Answer: Physical fitness.

Physical fitness can be achieved through a set diet, physical excersise (of course), rest, and many cardiovascular exercises. It is the ability of the body to successfully function efficiently during PA.

If you drive through water, your brakes may become slippery and ineffective. To dry the brakes off, __________.

GenaCL600 [577]

Answer:

Explanation:

Water at normal temperature is a good lubricant and will hinder the brake from working properly when the road is wet. To dry the brakes off, apply brakes gently as you accelerate. This will generate some heat that will evaporate the water with the help of friction.

Describe the formation of the land, the atmosphere, and the oceans of earth

Firlakuza [10]

Land: Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. ... Landforms can exist under water in the form of mountain ranges and basins under the sea.

Atmosphere: (4.6 billion years ago)
As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere. After about half a billion years, Earth's surface cooled and solidified enough for water to collect on it.

Ocean: After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.

A charged particle is placed in an external magnetic field and it is moving in a circular path of radius 26m.The magnetic force

ElenaW [278]

Answer:

208 Joules

Explanation:

The radius of the circular path the charge moves, r = 26 m

The magnetic force acting on the charge particle, F = 16 N

Centripetal force, $F_c$ = m·v²/r

Kinetic energy, K.E. = (1/2)·m·v²

Where;

m = The mass of the charged particle

v = The velocity of the charged particle

r = The radius of the path of the charged particle

Whereby the magnetic force acting on the charge particle = The centripetal force, we have;

F = $F_c$ = m·v²/r = 16 N

(1/2) × r × $F_c$ = (1/2) × r × m·v²/r = (1/2)·m·v² = K.E.

∴ (1/2) × r × $F_c$ = (1/2) × 26 m × 16 N = = (1/2)·m·v² = K.E.

∴ 208 Joules = K.E.

The kinetic energy of an particle moving in the circular path, K.E. = 208 Joules.

A 2. 5 kg block is launched along the ground by a spring with a spring constant of 56 N/m. The spring is initially compressed 0.

OLga [1]

The speed of the spring when it is released is 3.5 m/s.

The given parameters:

Mass of the block, m = 2.5 kg
Spring constant, k = 56 N/m
Extension of the spring, x = 0.75 m

The speed of the spring when it is released is calculated by applying the principle of conservation of energy as follows;

$K.E = U_x\\\\\frac{1}{2} mv^2 = \frac{1}{2} kx^2\\\\mv^2 = kx^2\\\\v^2 = \frac{kx^2}{m} \\\\v = \sqrt{\frac{kx^2}{m} } \\\\v = \sqrt{\frac{56 \times 0.75^2}{2.5} } \\\\v = 3.5 \ m/s$

Thus, the speed of the spring when it is released is 3.5 m/s.
