In a World Cup soccer match, Juan is running due north toward the goal with a speed of 7.60 m/s relative to the ground. A teamma

spayn [35]

Answer:

Part a)

$v_{bj} = 11.03 m/s$

Part b)

$\theta = 4.57 degree$ East of South

Explanation:

Part a)

Velocity of Juan is given as

$v_1 = 7.60 m/s \hat j$

velocity of the ball is given as

$v_2 = 12.9(cos31.4 \hat i + sin31.4\hat j)$

now we have

$v_2 = 11\hat i + 6.72\hat j$

Part a)

We need to find velocity of ball with respect to Juan

so it is given as

$v_{bJ} = \vec v_b - \vec v_j$

$v_{bj} = 11\hat i + 6.72 \hat j - 7.6\hat j$

$v_{bj} = 11\hat i - 0.88\hat j$

magnitude of the speed is given as

$v_{bj} = \sqrt{11^2 + 0.88^2}$

$v_{bj} = 11.03 m/s$

Part b)

direction of velocity of the ball

$tan\theta = \frac{v_y}{v_x}$

$tan\theta = \frac{-0.88}{11}$

$\theta = 4.57 degree$ East of South

The weight of an astronout is 60kg on earth, find the wight of the same object on the planet where the gravitational attraction

Marianna [84]

The astronaut's weight is not 60 kg anywhere, because kg is a unit of mass, not weight.

If the astronaut's mass is 60 kg, then his weight is (60 kg)x(acceleration of gravity).

That's 588 Newtons on Earth, and 58.8 Newtons on a planet with 1/10 Earth's gravity.

The astronaut's mass of 60 kg goes with her, and doesn't depend on where she is.

The volume of a gas is reduced when the temperature is decreased

Sloan [31]

Decreasing Pressure. The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.

In what ways would organisms living in very deep water need to be specialized?

Nady [450]

Organisms living in great depths of water bodies like oceans and lakes need to be adapted for two (2) things especially; high water pressure and vision in darkness

The water column above from deep in the water can cause lots of hydrostatic pressure on the organisms’ cells. Also the fact that light cannot penetrate to great depth of water due to diffusion means the organisms must live in darkness.

Explanation:

It has been shown that cells from Piezophile bacteria have a high percentage of fatty acids in their membranes to prevent the cells from compacting solid from the high pressure.

Most of the organisms are also detritivores and use chemosynthesis for the autotrophs because light cannot reach these depths and hence photosynthesis is not possible. Organisms with eye vision are adapted to high wavelength light that can at least reach greater depths before diffusing. Nonetheless natural selection would favour use of sight for most organisms in this benthic region.
