20 miles per hour north is an example of ______A) acceleration
B) velocity
C) deceleration
D) speed

Answers

B. It's an example of velocity due to the fact that it has a measurement of speed, divided by time, and has a specific direction. Acceleration doesn't have any direction on it, but has speed divided by time. C and D have a different mode of measurement despite of the fact that it still needs meters/miles/km.

The Hubble telescope’s orbit is 5.6 × 105 meters above Earth’s surface. The telescope has a mass of 1.1 × 104 kilograms. Earth exerts a gravitational force of 9.1 × 104 newtons on the telescope. The magnitude of Earth’s gravitational field strength at this location is

Answers


Gravitational force = 9.1 x 10⁴ newtons

Mass  =  1.1 x 10⁴ kilograms

Gravitational field strength =  9.1 x 10⁴ newtons / 1.1 x 10⁴ kilograms

                                      =  ( 9.1 / 1.1)  (newton / kilogram)

                                       =   8.3 newton/kg

                                       or  8.3 m/s² .

How and why can two lethal elements combine to form an essential
compound for health?

Answers

Answer:

Two lethal elements can combine to form an essential compound for health by undergoing a chemical reaction such that the properties of the individual elements are different from the properties of the product and are no more lethal

Example Mercury and Sulfur combine to form cinnabar which is used as a medicine to relieve pain, antiseptic, and to cure diseases

Mercury and sulfur combines because mercury readily combines with sulfur at high temperatures

Explanation:

Mercury is a lethal element that also has harmful effects on the neurological system

Sulfur is lethal when too much of it is consumed

A bottle lying on the windowsill falls off and takes 4.95 seconds to reach the ground. The distance from the windowsill to the ground is 120.00 meters. Find the time the bottle would take to land if it were to fall the same distance on the moon instead of Earth.

Answers

The time of the bottle would take to land if it were to fall the same distance on the moon instead of Earth is 12.12 seconds.

To find the Time, the given values are,

A bottle lying on the windowsill fall = 4.95 seconds

The distance of the object to the ground = 120 meters

What is the distance of the object?

The distance d an object falls under the influence of gravity is determined by the equation

                        D  =  (1/2) (g) (t²)

where,

D - Distance

g - acceleration of gravity

t²- square of the falling time

In the equation,

Multiply each side by  2 : 2 D = gt²

Divide each side by ' g ' : 2 D/g = t²

Square root each side: t = √ (2D/g)

Gravity on the surface of the moon is roughly  1/6  the value

of gravity on the surface of the Earth.

So we expect ' t ' to increase by  √6  =  2.45 times.

It would take the same bottle  (2.45 x 4.95) = 12.12 seconds

to roll off the same window sill and fall 120 meters down to the surface of the Earth.

Thus, the time of the bottle would take to land if it were to fall the same distance on the moon instead of Earth is 12.12 seconds.

#SPJ6

The distance an object falls from rest through gravity is

                         D  =  (1/2) (g) (t²)

            Distance  =  (1/2 acceleration of gravity) x (square of the falling time)

We want to see how the time will be affected
if  ' D ' doesn't change but ' g ' does.
So I'm going to start by rearranging the equation
to solve for ' t '.

                                                      D  =  (1/2) (g) (t²)

Multiply each side by  2 :         2 D  =            g    t² 

Divide each side by ' g ' :      2 D/g =                  t²

Square root each side:        t = √ (2D/g)


Looking at the equation now, we can see what happens
to ' t ' when only ' g ' changes: 

-- ' g ' is in the denominator; so bigger 'g' ==> shorter 't'
                                             and smaller 'g' ==> longer 't' .

-- They don't change by the same factor, because  1/g  is inside
the square root.  So 't' changes the same amount as  √1/g  does.

Gravity on the surface of the moon is roughly  1/6  the value
of gravity on the surface of the Earth.

So we expect ' t ' to increase by  √6  =  2.45 times.

It would take the same bottle  (2.45 x 4.95) = 12.12 seconds
to roll off the same window sill and fall 120 meters down to the
surface of the Moon.
