Answer:
An object in space that has no motion has to be shoved to move in the first place because of newton's first law of motion. A bowling ball will slow down and stop when rolled on a flat surface, like a street because of rolling friction which comes under Newton's first law of motion. When a 100Kg astronaut throws a 9Kg bowling ball forward in space, she moves backward but slower, this is because of Newton's third law of motion.Explanation:
This is due to Newton's first law of motion, explaining that an object in space that has no movement has to be moved to move in the first place. There is no external force or gravitational force in space, so the body can stay at rest and be forced to move first. Explaining why a bowling ball, like a street, can slow down and stop when rolled on a flat surface. This, again, is attributed to Newton's first law of motion. Due to rolling friction, it happens. The electrons on the surface of the ground in the atoms push against the electrons that touch the ground in the atoms on the surface of the ball as you roll a ball on the ground. A rolling ball stops when the surface on which it rolls opposes its motion. A ball rolling, due to friction, ceases.Explaining that when a 100 kg astronaut throws a 9 kg bowling ball forward in space, she travels backward but slower, due to Newton's third motion rule , which states that when force is applied, each body exhibits equal and opposite reaction. In this case, the astronaut's mass is greater, so the ball's acceleration will be less than the astronaut 's mass (since the body's mass is inversely proportional to the acceleration). Therefore, because of the reverse direction and slowly because of no gravitational force in space, the girl shifts backward while tossing the ball forward in space.Newton's Law of Motion -
FIRST LAW - The first law of Newton states that if a body is at rest or moving in a straight line at a constant speed, it will stay at rest or continue to travel at constant speed in a straight line unless it is acted upon by a force.
SECOND LAW - The second law of Newton is a quantitative explanation of the changes that a force can cause in a body 's motion. It states that the rate of change of a body's momentum in time is proportional to the force exerted on it in both magnitude and direction.
THIRD LAW - The third law of Newton notes that they apply forces to each other when two bodies interact, which are equal in magnitude and opposite in direction. Often known as the law of action and reaction, the third law is. In analyzing static equilibrium problems, where all forces are balanced, this law is essential, but it also applies to bodies in uniform or accelerated motion.
Hence , all the three explainations consist of newton's first and third laws of motion.

What is the magnitude of the relative angle φ
with which the ski jumper hits the slope?
Answer in units of ◦
.
Complete question is;
A ski jumper travels down a slope and leaves the ski track moving in the horizontal direction with a speed of 24 m/s. The landing incline below her falls off with a slope of θ = 59◦ . The acceleration of gravity is 9.8 m/s².
What is the magnitude of the relative angle φ with which the ski jumper hits the slope? Answer in units of ◦
Answer:
14.08°
Explanation:
The time covered will be given by the formula;
t = (2V_x•tan θ)/g
t = (2 × 24 × tan 59)/9.8
t = 8.152 s
Now, the slope of the flight path at the point of impact will be given by the formula;
tan α = V_y/V_x
We are given V_x = 24 m/s
V_y will be gotten from the formula;
v = gt
Thus;
V_y = gt
V_y = 9.8 × (8.152) = 78.89 m/s
Thus;
tan α = 78.89/24
tan α = 3.2871
α = tan^(-1) 3.2871
α = 73.08°
Thus ;
Relative angle φ = α - θ = 73.08 - 59 = 14.08°

A shopping cart given an initial velocity of 2.0 m/s undergoes a constant acceleration to a velocity of 13 m/s. What is the magnitude of the carts acceleration if the time is 4.0?
Also if your really smart and have instagram please dm imaswagmeal and help me pls
Answer:
The acceleration is a = 2.75 [m/s^2]
Explanation:
In order to solve this problem we must use kinematics equations.
[tex]v_{f} = v_{i} + a*t\\[/tex]
where:
Vf = final velocity = 13 [m/s]
Vi = initial velocity = 2 [m/s]
a = acceleration [m/s^2]
t = time = 4 [s]
Now replacing:
13 = 2 + (4*a)
(13 - 2) = 4*a
a = 2.75 [m/s^2]

Explanation:
Throughout the opposite direction, she not able to throw her tool-belt. In this scenario, she will be sending her floating through her ship. Unless interrupted, it could refer to Newton's The rule of it in motion remains in motion. Consequently, if they throw it one way because there are no molecules to interrupt your course, you can continue to go the other way.
How can parallax allow us to determine the distance to a star
Answer:
Astronomers use a method similar to the one you used with your homemade quadrant. Twice the distance to the Sun, divided by the distance to the star (which is unknown so far) is equal to the tangent of the parallax angle of the star.

Which is a vector quantity?
A distance
B. time
C.mass
D.velocity
Can anyone help,please?
Answer:
D. Velocity
Explanation:
Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

what happens to a circuits resistance, voltage, and current when you increase the diameter of the wire in the circuit?
The resistance increases as the diameter of the wire increases. Also, the voltage is constant and the current increases.
Resistance of a wireThe term resistance refers to the opposition offered to the flow of current by circuit elements. The resistance of a wire depends on its;
lengthCross-sectional areaNow, the diameter of the wire determines its cross sectional area. The resistance increases as the diameter of the wire increases. The voltage is constant and the current increases since voltage and current are directly proportional to each other. The correct answer therefore is option A.

Fermentation of glucose by yeast produces
A) ethyl alcohol and carbon dioxide.
B) lactic acid and carbon dioxide.
C) lactic acid and oxygen.
D) ethyl alcohol and oxygen.
Answer:
A
Explanation:
Ethanol fermentation causes bread dough to rise. Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it to a foam.
Fermentation of glucose by yeast produces ethyl alcohol and carbon dioxide. (option a)
Fermentation is a metabolic process that occurs in yeast and some other microorganisms when they lack oxygen. During this process, glucose, a simple sugar, is broken down into simpler compounds. The main goal of fermentation is to produce energy for the cell without the need for oxygen.
Yeast, a type of fungus, carries out alcoholic fermentation. In this process, yeast breaks down glucose into two primary products: ethyl alcohol (also known as ethanol) and carbon dioxide. The equation representing this fermentation process is as follows:
Glucose → Ethyl Alcohol + Carbon Dioxide + Energy
The carbon dioxide produced during fermentation is responsible for the formation of bubbles in dough, which causes bread to rise. It is also the reason behind the effervescence in alcoholic beverages like beer and champagne.
So, the correct option is (a).
