"For example, when you exercise you get hot. The heat you feel in your body results from the energy transfers that happen when you move. When you sweat, your body expends energy to cool itself down. A food chain shows how energy flows from one organism to another."

Which vector is the sum of vectors à and b?
Wittaler [7]

The vectors addition permits locating the perfect result for the sum of the two vectors in option B).  See attached and the vector is directed to the right and up.

Vector addition is the operation of adding or extra vectors together into a vector sum. The so-known as parallelogram regulation gives the rule for vector addition of or greater vectors. for two vectors and, the vector sum is received via placing them head to tail and drawing the vector from the loose tail to the unfastened head.

A vector is an amount or phenomenon that has impartial residences: importance and direction. The time period also denotes the mathematical or geometrical representation of the sort of quantity. Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight.

Vectors are used in technological know-how to describe something that has a direction and a magnitude. they're commonly drawn as pointed arrows, the length of which represents the vector's importance

point) A tank in the shape of an inverted right circular cone has height 5 meters and radius 4 meters. It is filled with 4 meter
zysi [14]

Answer:

W = 907963.50 J = 907.96 J

Explanation:

Note: Refer to the figure attached

Now, from the figure we have similar triangles ΔAOB and ΔCOD

we have

\frac{5}{4}=\frac{x}{r}

or

r=\frac{4x}{5}

Now, the work done to empty the tank can be given as:

W = \int\limits^4_0 {(5-x)\rho\times g A} \, dx

or

W = \int\limits^4_0 {(5-x)1080\times 9.8 (\pi r^2)} \, dx

or

W = \int\limits^4_0 {(5-x)\times10584\times (\pi (\frac{4x}{5})^2)} \, dx

or

W = 6773.76\pi\int\limits^4_0 {(5-x)x^2)} \, dx

or

W = 6773.76\pi[\frac{5}{3}x^3-\frac{1}{4}x^4]^4_0

or

W = 6773.76\pi[\frac{128}{3}]

or

W = 907963.50 J = 907.96 J

A car is traveling at 96km/hr. what is the acceleration of a car traveling a distance of 100m and come to rest?​
8090 [49]

Answer:

Explanation:

v² = u² + 2as

v = 0

u = 96 / 3.6 = 26.7 m/s

0² = 26.7² + 2a100

a = -3.5555555... ≈ -3.6 m/s²

the negative sign indicated the acceleration vector opposes the (assumed positive) initial velocity vector direction.
