Answer:

12,000 grams = 12 kg

Explanation:

Volume V = 20 x 20 x 30 cm³ = 12,000 cm³

density of water d = 1 g/cm³

so the mass is 12,000 grams = 12 kg

Answer:

F=k*x or

k is the spring constant, in Newtons per meter (N/m), and x is the displacement of the spring from its equilibrium position. The spring constant, k, is representative of how stiff the spring is. Stiffer (more difficult to stretch) springs have higher spring constant

Explanation:

Answer:

N/m

Explanation:

Spring force is defined as

F=kx

So,

the terms for spring constant can be rearranged to find

F/x =k

which simplifies to

N/m

since force F is in newtons, and displacement x is in meters.

Answer:

hold the plant in the ground

keep the plant upright

absorb water from the soil

take in nutrients from the soil

transport water and nutrients to the plant

provide a place for food storage

Explanation:

The plants are very complex organisms and can be classified into various types based on certain characteristics. The roots are very important structures which provide a lot of functions.

The roots are the important underground part of all the vascular plants. This part of the plant is generally responsible for anchoring it down into the ground and absorbing all the essential minerals, nutrients, and water from the soil.

The root of the plant also help us to store the food. The roots are not the reproductive part of the plants, they are called the vegetative parts. In certain plants, the roots are the means of reproduction. This type of reproduction is called the vegetative reproduction.

The roots also check the soil erosion, provide sustenance and also habitat for various organisms. The root absorb water and minerals from the soil and help in the process of photosynthesis.

Answer:

Cyberpunk has worst Physics

Explanation:

The box will undergo an acceleration. Due to Newton's 3rd Law, any action causes an equal and opposite reaction. The equal and opposite force from the box will not cancel the force that you are applying.

Answer:

The box will not move as it is in a a stable condition

Explanation:

when an equal and opposite force acts on a body the effects of forces cancels out. provided the body can withstand the tensile and compressive actions of the forces. when both forces are coming together it leads to compression while tension refers to forces moving away fro, each other.

Explanation:

If the distance is reduced by factor of 2, lets say the distance was 10cm

reducing by a factor of 2 will leave the distance at 5cm

so the electric force increases by a factor of 2

Answer:

0.065 seconds

Explanation:

i) Change in momentum is equal to impulse so, m(v-u) = ft  (Where f is force and t is time)

ii) Since we know the mass of the ball, we change grams to the SI unit of kilograms, kg so 0.057kg

iii) We are also told that the ball CHANGES direction, so we know that the new velocity is the negative value of the initial one,

iv) Putting this all together we get 0.057(25--15) which is the same as 0.057(25 + 15)

v) We get an impulse of 2.28 Ns

vi) We take this value and divide it by 35 as we want the Force alone and not the time,

vii) To which we get 0.065 seconds,

Answer:

9m/s

Explanation:

Average velovity= (Initial velocity+Final velocity)/2

or A.V=(0+18)/2

or A.V= 9m/s

A sprinter starting from rest reaches final velocity of 18.0 mi/h. The average velocity of the sprinter is 9.0 mi/h.

Given that the sprinter starts from rest and reaches a final velocity of 18.0 mi/h, we can assume that the sprinter accelerates uniformly. Therefore, her average velocity would be the average of her initial velocity (0 mi/h) and her final velocity (18.0 mi/h).

Average velocity = (Initial velocity + Final velocity) / 2

Average velocity = (0 mi/h + 18.0 mi/h) / 2

Average velocity = 18.0 mi/h / 2

Average velocity = 9.0 mi/h

Question Parameters:

the basket and player are of the same height.

He shoots the ball at angle 45 o

The height covered through the trajectory is 2.05 m 0 = 45°

The ball will create a parabolic shape to make a basket

Generally, the equation for the projectile motion is mathematically given as

y = (tan θ0)x – gx2/2(v0cosθ0)2

Answer:

because the friction/movement of the bikes wheels, generates electricity and energy that the light can use to generate electricity and it also does not have a battery on it and relies on the wheels to generate the electricity for the light to work.

Explanation:

A low latitude, the energy transferred from the sun is high while at a high altitude the energy transferred from the sun is low.

Latitude is an angle which ranges from 0 degree at the Equator to 90 degrees at the poles of the Earth.

At higher latitudes, the sun's rays are less direct and a lower latitude the ray's of the sun are more direct. The farther an area is from the equator, the lower its temperature.

Thus, a low latitude, the energy transferred from the sun is high while at a high altitude the energy transferred from the sun is low.

Explanation:

The law of conservation of energy supports climate change research because the energy we use is released into the atmosphere, creating loop of continual absorption and releasing of heat.

The law states that energy can neither be created nor destroyed but can always be converted from one form to another.

In light of this, any energy used by humans or natural processes is not destroyed. Instead, they are converted into another form or released into the atmosphere.

In the atmosphere, absorption and release of heat energy by greenhouse gases and irradiation create a loop. This loop causes a net heating or cooling of the planet, a phenomenon that affects the climate.
