The impact of the type of material of which the slope is made on acceleration

1 answer:

Pachacha [2.7K]3 years ago

6 0

The impact of the material type with which the slope is made affects the acceleration. Acceleration will be higher and smoother if the material of the slope surface is smoother as opposed to a texture which is not smooth. Smoother surface allows more acceleration because it will have less friction and resistance. Otherwise the friction will slow the object down for example a grassy ground will have more friction than a well maintained marble floor.

The carbon cycle is powered by which two processes?

Arada [10]

Answer:

the answer is the last one

Explanation:

here is the definition:

(i know how to explain the answer, its merely unnecessary being that there is an offical definition.)

<em>the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.</em>

Two particles with masses m and 3m are moving toward each other along the x axis with the same initial speeds Vi. Particle m is

nignag [31]

Answer:

$v1 = \sqrt{(2)}Vi$

$v2 = \sqrt{(2/3)}Vi$

ANGLE is 35.3 degree celcius

Explanation:

Given data:

mass m and 3m

initial speed Vi

particle with mass m is moving toward left while particle with mass 3m is moving toward right

By using conservation of momentum :

$mVi + 3m(-Vi) = mv1 +3mv2$

$-2mVi = m(v1 + 3v2)$

$-2Vi = v1 + 3v2$

conservation of energy :

$m(Vi^2) + 3m(-Vi^2) = mv1^2 + 3mv2^2$

$4mVi^2 = m(v1^2+3v2^2)$

$4Vi^2 = v1^2+3v2^2$

After collision, particle with mass m moves at right angles, thus by considering conservation of momentum in x & y direction,

x direction : $-2mVi = 3m.v2i$

$-2Vi = 3v2i$

y direction : $0 = m(v1)j+3m(v2)j$

$-v1j = 3v2j$

subsitute these value in energy conservation

$v1 = \sqrt{(2)}Vi$

$v2 = \sqrt{(2/3)}Vi$

$angle = tan^{-1}(\frac{\sqrt{(2)}}{2}) =$ 35.3 degree from x-axis

soldi70 [24.7K]

Answer:

$F_m= 8.28 \times 10^{-16} N$

Explanation:

The magnitude of the force is $F_m=evB\sin\theta\\\implies F_m=1.602 \times 10^{-19}\times 300\times 19\times\sin 65^0= 8.28 \times 10^{-16} N$

If a team pulls with a combined force of 4 newtons on an airplace with a mass of 36 kilograms,what is the acceleration of the ai

MatroZZZ [7]

Heya!!

For calculate aceleration, lets applicate second law of Newton:

$\boxed{F=ma}$

<u>Δ Being Δ</u>

F = Force = 4 N

m = mass = 36 kg

a = Aceleration = ?

⇒ Let's replace according the formula:

$\boxed{4\ N = 36\ kg * \textbf{a}}$

⇒ Clear acceleration and resolve it:

$\boxed{\textbf{a}=0,111\ m/s^{2}}}$

Result:

The aceleration is of <u>0,111 meters per second squared (m/s²)</u>

Good Luck!!
