Answer:

The answer is Radiation.

Explanation:

The phenomenon of radiation is the propagation of energy in the form of electromagnetic waves or subatomic particles through vacuum or a material medium. Solar radiation is the set of electromagnetic radiation emitted by the Sun and which reach the earth, although not all radiation reaches the Earth's surface, because the shortest ultraviolet waves are absorbed by the gases of the atmosphere. The magnitude that measures the solar radiation that reaches the Earth is the irradiance, which measures the power that per unit of surface reaches the Earth.

AleksandrR [38]

Answer:

304.86 metres

Explanation:

The x and y cordinates are $dcos\theta$ and $dsin\theta$ respectively

The horizontal distance travelled, $x=v_{ox}t=dcos\theta$

Making t the subject, $t=\frac{dcos\theta}{v_{ox}}$

Since $y=0.5gt^2=dsin\theta$ , we substitute t with the above and obtain

$0.5g(\frac{dcos\theta}{v_{ox}})^2=dsin\theta$

Making d the subject we obtain

$d=\frac{2v_{ox}^2sin\theta}{gcos^2\theta}$

$d=\frac{2*30^2sin48}{9.8cos^248}$

d=304.8584

d=304.86m

A 7.00-kg object undergoes an acceleration given by ax=3.00 and ay= 9.00 m/s2. Find (a) the components of the force acting on th

lord [1]

Answer:

66.4 N

Explanation:

From Newton's second law, F = ma

where F is the force, m is the mass and a is the acceleration.

Because the object has acceleration in two directions and the mass is constant, the force will be in two directions. The component of the forces are:

$F_x = ma_x = (7.00\text{ kg})(3.00 \text{ m/s}^2) = 21.0\text{ N}$

$F_y = ma_y = (7.00\text{ kg})(9.00 \text{ m/s}^2) = 63.0\text{ N}$

The magnitude of the resultant force is given by

$F = \sqrt{F_x^2+F_y^2}$

$F = \sqrt{(21.0\text{ N})^2+(63.0\text{ N})^2} = \sqrt{(441.0\text{ N}^2)+(3969.0\text{ N}^2)} = \sqrt{(4410\text{ N}^2)} = 66.4 \text{ N}$

Answer:

The requested distance is 4320 meters

Explanation:

We can use the formula for velocity in this movement at constant velocity (v), which is defined as the quotient between the distance covered divided the time it took:

$v=\frac{distance}{time}$
