Answer:
Bananas are curved because they grow towards the sun
Explanation:
Bananas are curved so they can retrieve sunlight. Bananas go through a process called 'negative geotropism'. What it means is that bananas grow away from the ground, instead of growing towards it, hence the 'negative' geotropism.
Answer:
Because they grow towards the sun and the sun is what makes things grow like water to Beneath each flower petal, a row of tiny banana fruits start to grow. Once they're much bigger in size, the fruit goes through a process called negative geotropism. Which basically means instead of continuously grow towards the ground, they start to turn towards the sun, in order to retrieve light.

2) Displacement is 2 m west; distance is 22 m
3) Displacement is 7 m east; distance is 25 m
4) Displacement is 4 m west; distance is 20 m
Answer:
A=4
B=3
c=2
D=1
Explanation:
since the person moving in opposite direction so displacement =distance in east/west - distance in west/east

Explanation:
The mass of mass A the diagram .the frame joining the mass is massless.
What is Mass?The unique location in an object or system that can be used to describe how the system reacts to outside forces and torques is referred to as the "center of mass" or "center of gravity" in a uniform gravity field.
The idea of the center of mass is that it is the average of all the masses divided by the distances between them. With regard to the torques produced, that is comparable to balancing a seesaw around a pivot point in one plane.
Therefore, The mass of mass A the diagram .the frame joining the mass is massless.

Explanation:
If the reference point changes, the ______ of position changes, but the actual position does not change
Answer:
Description.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.
Hence, if the reference point changes, the description of position changes, but the actual position does not change.

If you use a lever to lift a boulder 0.25m, while applying 350 N on the lever which moves 1.5 m down on your side. What is the weight of the boulder? (F1d1 = F2d2) 87.5 N 131 N 525 N 2100 N
Answer:
2100 N
Explanation:
From the question,
Using the formula
F₁d₁ = F₂d₂..................... Equation 1
Where F₁ = Weight of the Boulder, d₁ = distance moved by the Boulder, F₂ = Force applied on the lever, d₂ = distance moved by the lever.
make F₁ the subject of the equation
F₁ = F₂d₂/d₁.................... Equation 2
Given: F₂ = 350 N, d₁ = 0.25 m, d₂ = 1.5 m
Substitute these values into equation 2
F₁ = 350(1.5)/0.25
F₁ = 2100 N

The Universe in the future have two possibilities:
The Universe will come to an end in the opposite of a Big Bang called The Big Crunch. The other possibility is that we live in an Eternal Universe that will never come to end.What is universe?Universe is the whole cosmic system of matter and energy. The Earth, the Sun, the Moon, the planets, the stars along with the dust , gases, rocks forms the universe.
The big bang is the theory which explains that how the universe began. It says that the universe began with just a single point. It went on expanding and stretched to grow as large as possible. It is still now expanding.
The universe consist of fully dark matter, interstellar gases or dust. The big bang is increasing just because in universe there is abundant of hydrogen and helium. The two possibilities:

An object has a kinetic energy of 50 J and a velocity of 5 m/s, what is the mass of the object?
Answer:
Mass, M = 4 kilograms.
Explanation:
Given the following data;
Kinetic energy = 50 J
Velocity = 5 m/s
To find the mass of the object;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Making mass the subject formula;
[tex] M = \frac{2K.E}{V^{2}}[/tex]
Substituting into the equation, we have;
[tex] M = \frac{2*50}{5^{2}}[/tex]
[tex] M = \frac{100}{25}[/tex]
Mass, M = 4 kg

An old woman is worried about time. She walks at a rate of 2 meters per second and travels a
distance of 454 meters. How long does it take her to complete the motion?
Please help ASAP!! BRAINLIST please explain thankyou!!!
Answer:
227 seconds.
Explanation:
Speed is equal to distance divided by time. s = d/t
We can rearrange this algebraically to solve for the time it will take to cover a certain distance at a certain speed. Time is equal to distance divided by speed. t = d/s
Then we substiture our known values for the variables and solve for our unknown.
t = 454m / 2m/s = 227s
Answer:
If the lady is traveling 2 meters per second and she travels 454 meters then you will have to divide 454 by 2 to get the amount of time she walked.
454 divided by 2 = 227
This means that the lady traveled for 227 seconds or about 3.78 minutes.
What role does the sun play in driving the water cycle in Antarctica
Answer:
the inner regions of antarctica gets only about 2 inches of precipitation per year. the winds here blow up snow from the land and put it into the atmosphere, which is part of the water cycle. and the sun helps out, too, causing sublimation to occur, which causes snow to evaporate directly into water vapor gas.

If a 7 kg bowling ball is lifted 2 m into the air and dropped, what speed will it strike the ground? (
Answer:
6.32m/s
Explanation:
note:Now these calculations are based in the fact that acc. due to gravity is 10m/s²
okay so I'm thinking you think the speed of a body depends on the mass of the body also,umh... well it doesn't at all!
when two bodies of different masses fall from the same height,they fall at the same time( this is just to say)
now enough of the talking let solve....
so the ball was dropped .ie from rest to the ground through a distance of 2m,
the formula for calculating the distance if a body moving in a straight line is given by:
S=ut + ½at² where u is initial velocity, a is acceleration ( of the body or due to gravity, but since its falling freely under the influence of gravity its " we use the acceleration due to gravity ,which is 10m/s²) and t is the time taken to cover the distance.
from our question the ball was dropped from rest thus its u is 0 therefore we use this equation to find the time it took to touch ground (S=½at²)
solving ....
we get t to be 0.632s
to find the speed we substitute t in the equation below:
V=u+at ,but since u=0
V=at =10•0.632=6.32m/s
therefore the speed the body uses to strike the ground is 6.32m/s
