Radiant to Chemical, is a good example of energy transformation. An example can be solar energy, or the sun, converting into sugar for a chlorophyll based organism, like plants. In which the plant takes in the sun's rays into its leaves, and uses it to transform nutrients from water and the soil to turn into surgar for itself.

Natasha_Volkova [10]

Difference between the mean of the data, including the outlier and excluding the outlier is;

B: 0.93

<h3>Mean average</h3>

Her time in minutes for the given months are;

January = 41.55 minutes
July = 36. 38 minutes
Feb = 42.51 minutes
Aug = 38.48 minutes
Mar = 43. 01 minutes
Sept = 41.87 minutes
Apr = 39. 76 minutes
Oct = 51.32 minutes
May = 37. 32 minutes
Nov = 42.59 minutes
June = 35.28 minutes
Dec = 43.71 minutes

Looking at all the numbers, they largely range from 36 to 44 which means that the outlier is 51.32

Total number of minutes with outlier = 493.78 minutes

Number of months = 12

Thus;

Mean with outlier = 493.78/12

Mean with outlier = 41.15 minutes

Mean without outlier = (493.78 - 51.32)/(12 - 1)

Mean without outlier = 40.22 minutes

Thus;

Difference in both means = 41.15 - 40.22

Difference = 0.93

A pendulum is made by tying a 75 g ball to a 130-cm-long string. the ball is pulled 5.0∘ to the side and released.

Maslowich

The ball’s speed and direction at the lowest point of trajectory are; 3.1 m/s and swing to the same angle on the other side

<h3>What is the speed at the lowest point?</h3>

We will assume that all of the motion will transfer to Kinetic Energy at the lowest point. Now, the difference in height will be;

Δh = (130 – 130*cos °5) = 0.49 cm

The change in PE is;

ΔP.E = mgΔh

ΔP.E = 9.8m/s² × 0.75kg × 0.049 m

ΔP.E = 0.36015 J

Formula for kinetic energy is;

K.E = ¹/₂*m*v²

From conservation of energy;

K.E = P.E

Thus;

¹/₂* 0.075 * v² = 0.36015

v = √[(0.36015 * 2)/0.075]

v = 3.1 m/s

Thus, the pendulum will swing to the same angle on the other side.

An object is moving due north at 32m/s. does this tell you the speed or the velocity of the object, or both?

xxMikexx [17]

An object is moving due north at 32m/s. then this tells about the velocity of the object as it has the direction.

<h3>What is the difference between velocity and speed?</h3>

The immediate velocity of an item is then the value of its immediate pace. Speed tells you the way rapid. Velocity tells you the way rapid and in what route.

When you realize each velocity and route of an item's motion, you realize the speed of the item. Velocity tells us the velocity and route of a shifting item. Acceleration tells us the charge at which the pace changes.
