1 answer:

8 0

Hey there!

Since you didn't provide that much information that we can solve for our answer

" $21,769$ to $1$ decimal place (aka $tenths$ ) would most likely be: $21,769.0$

Good luck on your assignment and enjoy your day

10. What two shapes make up a sphere?<br> A. B.

Mashutka [201]

Answer: B

Explanation: A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball (viz., analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk"). Like a circle in a two-dimensional space, a sphere is defined mathematically ... This distance r is the radius of the ball, which is made up from all points.

What is the irradiance measured at a distance of 1 m and 2 m from a 1 W light point source

Paul [167]

Using the concepto of Irradiance which is the radiant flux (power) received by a surface per unit area we have that,

$I = \frac{P}{A}$

Here,

P = Power

A = Area

The propagation of the irradiance is carried out in an area proportional to that of a sphere we will then have,

$I = \frac{P}{4\pi r^2}$

Irradiance at a distance of 1m from the source of light is

$I = \frac{1W}{4\pi (1)^2}$

$I = 0.0796W/m^2$

$I = 0.08W/m^2$

Irradiance at a distance of 2m from the source of light is

$I = \frac{1W}{4\pi 2^2}$

$I = 0.0198W/m^2$

$I = 0.02W/m^2$

A person is attracted toward the centerof the earth by a 500 n gravitational force. the force with which the earth is attracted

nignag [31]

500 N is the answer, you just tell that the moon is attracted towards the person because of the Earth's huge mass.

A ball rolls off the edge of a table with a fairly large horizontal velocity. Which of the following statements are true? (Selec

Degger [83]

Answer:

A.The vertical velocity is constantly increasing as the ball falls.

B.The horizontal velocity does not noticeably change as the ball falls.

G.The horizontal velocity does not affect how long it will take the ball to fall to the floor.

H.The velocity vector of the ball changes as it travels through the air.

Explanation:

As the ball is projected horizontally so here the vertical component of the velocity is zero

So the time to reach the ground is given as

$H = \frac{1}{2} gt^2$

so we will have

$t = \sqrt{\frac{2H}{g}}$

so this is the same time as the ball is dropped from H height

Since there is no force in horizontal direction so its horizontal velocity will always remain constant while vertical velocity will change at constant rate which is equal to acceleration due to gravity.

So overall the velocity vector will change due to net acceleration g
