Patty decides to try another experiment. From the
same branch, she drops a large, heavy rock and a
small pebble. What would happen this time?
Answer: They will fall at the same time
Explanation:I had a google doc about this
When air resistance is considered, the effect of the air resistance will cause the rock to fall faster than the pebble which will be delayed due to its lesser weight. In the absence of air resistance, both rock and pebble will fall down at the same time.
What are free fall and air resistance?Free fall is a motion of an object in which the force of gravity is the only force acting upon it. A body moving upwards would not be considered to be falling. But if the body falls under the effect of the force of gravity, it is said to be in free fall.
Free fall is a type of motion in which no air resistance is considered and the force acting upon an object is only gravity. All bodies under such conditions fall with an equal rate of acceleration, regardless of their masses.
As a body falls through the air, have suffered some degree of air resistance. Air resistance is the collisions of the surface of an object with molecules present in the air. The factors that have a direct effect on the amount of air resistance are the cross-sectional area and the speed of the object.
As the rock had greater weight than the pebble in the absence of air resistance it will fall faster than the pebble.

2. The Himalayas in central Asia are the tallest mountains in the world. But fossils of seashells can be found high in these mountains, far from any ocean.
How do you think they got there?
Answer:
The sea level could have been much higher in the past.
Explanation:
The tectonic plates shifted and the mountain rose from there.
They are trapped throughout the rock whereas the seashells have been on the floor of a modest seafloor.
These same containers dropped down on the base of the silt level or sheet, as well as those layering finally became rock.Few more million generations previously, the Indian civilization or the subcontinent crashed well with the continents of Asia, making the Himalayan mountains rock which thus previously were such a sea level.
Thus the above response is appropriate.

A ball is thrown vertically upwards from a point on the ground. It was observed at a height h twice with a time interval Δt. The initial velocity of the ball is?
how much faster will a car be going if it accelerates at 1 m/s/s for a total of 60 seconds.
Answer:
Vf = 60 [m/s]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f}= v_{i}+(a*t)[/tex]
where:
Vf = final velocity [m/s]
Vi = initial velocity = 0
a = acceleration = 1 [m/s^2]
t = time = 60 [m]
Now replacing:
Vf = 0 + (1*60)
Vf = 60 [m/s]
Why is the nucleus positive in charge?
Answer:
The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

Considering the activity series given for nonmetals, what is the result of the below reaction? Use the activity series provided. F > Cl > Br > I
Br2 + NaF Right arrow.
no reaction
Na + FBr2
NaBr + F2
Na2F + Br2
Answer:
A.) no reaction. Edge 2020.
Explanation:
There will be no reaction.
The activity series is also known as the reactivity series. It arranges elements in order of reactivity.
Given the activity series; F > Cl > Br > I, we need to predict whether the reaction; Br2 + NaF will proceed or not.
Looking at the reaction, Br is less than F in the activity series so Br can not displace F in NaF. Hence, there will be no reaction.

A baseball is hit into the air with a velocity of 27 m/s. How high does it go?
Answer:
Explanation:
If a baseball is hit into the air with a velocity of 27 m/s, we want to determine the maximum height of the ball. Using the projecile formula;
Max height H = u²/2g
u is the initial velocity of the body = 27m/s
g is the acceleration due to gravity = 9.81m/s²
H = 27²/2(9.81)
H = 729/19.62
H = 37.16m
Hence the ball went 37.16m high

Explanation:
The speed of an object changes only when it is acted on by an unbalanced force.
Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion.

Which type of energy is stored in a battery?
O A. Nuclear energy
O B. Electrical energy
O C. Electromagnetic energy
O D. Chemical energy
Answer:
Chemical energy is in a battery
The type of energy is stored in a battery is Chemical energy (option d)
Batteries store chemical energy. When a battery is charged, a chemical reaction occurs inside it, converting the reactants into different products. This process stores energy in the form of chemical bonds within the battery's components.
When you use the battery to power a device, the reverse chemical reaction takes place, releasing the stored energy as electrical energy. This flow of electrons creates an electric current that powers the device connected to the battery.
The capacity of a battery to store and release energy depends on the type and quantity of chemicals used in its construction. Different types of batteries, such as alkaline, lithium-ion, or lead-acid batteries, have varying chemical compositions, affecting their energy storage capabilities and overall performance.
So, the correct option is (d).

A man weighing 490N on earth weighs 81.7N on the moon.His mass on the moon is kg
His mass is 50 kg . . . on the Moon, on the Earth, in the capsule rocketing between them, and on Halley's comet if he ever goes there.
Answer:
50kg
Explanation:
The mass of a man on the Earth and the moon is the same, so we only need to use the 490N weight on Earth.
The formula for mass is m=w/g. Plugging in the values, we can determine that m=490N/9.8m/s^2. (g is gravitational constant, which is approximately 9.8m/s^2 on Earth)
The reason that the unit in the answer is in kg is because one newton (N) is 1kg*m/s^2. The m/s^2 is cancelled out by the m/s^2 in the gravity constant, so it leaves kg.
m=50kg
