Explanation:
Given
Mass(M) = 80,000 kg
Acceleration (a) = 35 m/s²
Force (F) = ?
We know we have the formula
F = m * a
= 80000 * 35
= 2800000
= 2.8 * 10 ^ 6 N
The force is 2.8 * 10 ^ 6 N.
Hope it will help :)❤
If a rocket has a mass of 80,000 kg and accelerates at a rate of 35 m/s2. then the force that provides this acceleration would be 2800000 Newtons.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
The mathematical expression for Newton's second law is as follows,
F = m*a
As given in the problem we have to find the force that provides the acceleration of 35 meters / second², if the rocket has a mass of 80,000 kg,
The force acting on the rocket = 80,000 × 35
= 2800000 Newtons
Thus, the force acting on the rocket would be 2800000 Newtons.

Zad. 2 W marszobiegu chłopiec przebiegł 900 m w ciągu 205 min, a następnie przeszedł 300m w tym danym czasie. Jaka była średnia prędkość chłopca podczas marszobiegu?
Odpowiedź:
0,049 m / s
Wyjaśnienie:
Biorąc pod uwagę, że:
Dystans biegu = 900m
Czas trwania = 205 minut
Długość przejścia = 300 m
Zajęty czas = 205 minut
Średnia prędkość :
(Przebieg + pokonany dystans) / całkowity czas
Średnia prędkość :
(900 m +. 300 m) / 205 + 205
1200 m / 410 minut
Minuty do sekund
1200 / (410 * 60)
1200/24600
= 0,0487804
= 0,049 m / s

all energy,potential kinetic within a specific system
a)joule
b) total energy
c) potential energy
Answer:
C
Explanation:
The potential and kinetic energy within a specific system is called the total energy of the system.
Option B is the correct answer.
Potential and Kinetic EnergyThe energy of the specific system due to its steady position is defined as the potential energy of the system.
The energy of the system which is stored due to the motion of the system is called the kinetic energy of the system.
The mechanical energy of the system is the total energy within the system including its kinetic and potential energy.
The sum of kinetic and potential energy is known as mechanical energy. An object's mechanical energy is defined as the total energy which is stored during its steady position and stored during the motion of the object.
Hence we can conclude that option B represents the correct answer for the given statement.

Flag In reaching her destination, a backpacker walks with an average velocity of 1.34 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.68 m/s, due west, urns around, and hikes with an average velocity of 0.447 m/s, due east. (a) How far east did she walk? (b) If she did not turn around and walked due east, how many hours would it take her to reach her destination with an average velocity of 1.34m/s due west?
Answer:
[tex]s_2=-806m[/tex]
Explanation:
From the question we are told that
Velocity 1 [tex]v=1.34m/s \angle west[/tex]
Distance [tex]d=6.44km=>6440m[/tex]
Velocity 2 [tex]v_3=2.68m/s[/tex]
Velocity 3 [tex]v_3=0.447m/s \angle east[/tex]
Generally the equation for VT is mathematically given by
[tex]VT=v_1t_1 +V_2t_2[/tex]
[tex]VT=2.68(2400)-0.447t_2[/tex]
[tex]1.34t_1+1.34t_2=2.68(2400)-0.447t_2[/tex]
[tex]t_2=1804s[/tex]
Therefore
[tex]s_2=v_2t_2=(-0.447)(1804)[/tex]
[tex]s_2=-806m[/tex]

What conditions would you expect to find during an effusive eruption?
Answer:
Effusive eruptions occur when hot, (1200oC) runny basalt magmas reach the surface. Dissolved gases escape easily as the magma erupts, forming lava that flows downhill quite easily. Effusive eruptions build up gently-sloping Shield Volcanoes like Hawaii.

Two charges separated by one meter exert a 9 N force on each other. If the charges are pushed to a 3 meter separation, the force on each charge will be 3 N.
True or False?
Answer:
False
Explanation:
The formula of force that exists between two charges is expressed as;
F = kq1q2/r²
If two charges separated by one meter exert a 9 N force on each other, the;
9 = kq1q2/1²
9 = kq1q2 ..... 1
If the charges are pushed to a 3 meter separation, then;
F = kq1q2/3²
F = kq1q2/9 .... 2
Divide both equations;
9/F = (kq1q2)/ kq1q2/9
9/F = kq1q2 * 9/ kq1q2
9/F = 9
F = 9/9
F = 1N
Hence if the charges are pushed to a 3 meter separation, then the force on EACH charge will be 1N. Hence the answer is False

Answer:
36g
Explanation:
Given parameters:
Number of moles of H₂O = 2moles
Unknown:
Mass of H₂O = ?
Solution:
To solve this problem, use the expression below:
Mass of H₂O = number of moles x molar mass
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of H₂O = 2 x 18 = 36g

The whale shark the largest of fish and can have the mass of three adult elephants. Suppose that a crane is whale shark into a tank for delivery to an aquariumThe crane must exert an unbalanced force of 2.5 * 10 ^ 4 to lift the shark from rest. If the shark's acceleration equals 1.25 m/s ^ 2 , what is the shark's mass?
Answer:
Mass, m = 20000 kg
Explanation:
The force acting on the shark, [tex]F=2.5\times 10^4\ N[/tex]
Acceleration of the shark, a = 1.25 m/s²
We need to find the mass of the Shark. The force acting on an object is given by :
F = ma
m is the shark's mass
So,
[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg[/tex]
So, the mass of the Shark is 20000 kg.
A book is resting on a table. The table is raised on one end to an angle of 15° to the floor. If the book remains at rest, what keeps the book from sliding?
A. rolling friction
B. static friction
C. sliding friction
D. fluid friction
Answer: Static Friction
Explanation: As you tilt the book you know that it will stay fixed to start with, but eventually, once the angle is large enough, the book will start to slide. It is the static friction force that holds the book in place at small angles of tilt.
The book remains at rest if A book is resting on a table. The table is raised on one end to an angle of 15° to the floor due to static friction, so option C is correct.
What is static friction?An item is kept at rest by the force of static friction. The phrase "static friction" can be defined as "the friction people perceive when they attempt to move a stationary object on a surface, but without actually causing any relative motion between the body and the surface it is on."
You can predict that the book will initially remain fixed when you tilt it, but once the angle is sufficiently large, it will finally begin to slide. The book is held in place at slight tilt angles by static friction force.
The formula for the coefficient of static friction is μ = tan θ, here θ is the angle of inclination if the angle is bigger the friction force is more but at 90° when the book is vertical then the friction force will not work on the book
Therefore, the book remains at rest if A book is resting on a table. The table is raised on one end to an angle of 15° to the floor due to static friction.

A toy car is allowed to roll down a ramp during an experiment. While it is on the ramp, gravity acts on the car as an unbalanced force. Which of the following graphs best illustrates the car’s velocity as a function of time while it is on the ramp?
Answer:
When an unbalanced force acts on an object, the motion of the object is changed. If the object is at rest, the force makes it move. If the object is in motion, the force changes its velocity. Any change in velocity is acceleration

If the half-life of tritium (hydrogen-3) is 12.3 years, how much of
a 10 g sample of tritium is present after 250.0 years?
Answer:
0.0000076 grams
Explanation:
We're given the half life of Tritium to be 12.3 years. In order to find out the amount of substabce remaining:
Let's first find how many 'half lives' are in 250 years.
[tex]n = \frac{250}{12.3} = 20.325[/tex]
Now what is half life? It means the time taken for a given quantity of an element to lose half it's mass.
So in 12.3 years we can find that The amount of 250 g of Tritium will be 250/2 = 125 g. In 24.6 years we'll have 125/2 = 62.5 g
So now we can devise a formula:
[tex]m = \frac{original \: amount}{ {2}^{n} } [/tex]
Where m is the remaining amount and n is th number of half lives in the time given.
Using this formula we can calculate:
[tex]m = \frac{10}{ {2}^{20.325} } [/tex]
Doing this calculation we get:
[tex]m = 0.0000076 \: g[/tex]
As we can see a very small value remains.
