A space-walking astronaut has become detached from her spaceship. She's floating in space while holding a wrench. She is thinking about how she might get back to the ship, which she can see 50 m from her current location. Which of Newton's three laws will help her the most to get back to the ship?
Answer:
please find the solution which is defined as follows:
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.
Lisa has a mass of 52 kilograms. How much does Lisa weigh in Newtons? How much does she weigh in pounds? (Use g = 9.8 m/s)
Answer: 510 in Newton’s and 115 lbs
Explanation:
Considering the definition of weigh, Lisa weighs 0.5096 N or 0.1146 pounds.
Mass is the amount of matter that a body contains, while weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.
The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.
Weight can be calculated as the product of mass and acceleration due to gravity:
W=m×g
In this case, you know:
m= 52 g= 0.052 kg (being 1000 g=1 kg)g=9.8 m/s²Replacing in the definition of weigh:
W=0.052 kg×9.8 m/s²
Solving:
W= 0.5096 N
1 newton equals 0.2248 pound. Then W=0.5096 N= 0.1146 Pounds
Finally, Lisa weighs 0.5096 N or 0.1146 pounds.

If a person pulls a cart to the right at 5N of force and another person pulls to the left with a 15N of force? What is the net force and it what direction
Answer:
The net force is 10 [N] acting to the left
Explanation:
To solve this type of problem we must make a sum of the forces acting on the cart, since the forces are vectors, we know that vectors can be added, In this way forces that go in the same direction are added and forces in opposite directions are subtracted.
FL = force to the left = - 15 [N]
FR = force to the right = 5 [N]
FT = Resultant force [N]
- 15 + 5 = FT
FT = - 10 [N]
The negative sign tells us that the force acts to the left.

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.

An object is thrown downward from the top of a 175 meter building with an initial speed of 10m/s
Answer:
Explanation:
we can look for the final velocity of the object using the eqaution of motion as shown:
v² = u²+2gH
v is the final velocity
u is the initial velocity = 10m/s
g is the acceleration due to gravity = 9.81m/s²
H is the height of the object = 175m
Subxtitute the given parameters inti the formula and get v:
v² = 10²+2(9.81)(175)
v² = 100+3433.5
v² = 3533.5
v = √3533.5
v = 59.44m/s
Hence the final velocity of the object is 59.44m/s

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]

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).

How much energy must be absorbed by water with a mass of 0.5 kg in order to raise the temperature from 30°c to 65°C?
Water has a specific heat of 4,190 j/kg°C
Answer:
Q = 67.04 [J]
Explanation:
In order to solve this problem, we must use the following equation of thermal energy, which relates mass to specific heat and temperature change.
[tex]Q = m*c_{p}*(T_{2} -T_{1})[/tex]
where:
Q = thermal energy [J]
m = mass = 0.5 [kg]
Cp = specific heat = 4,190 [J/kg°C]
T2 = final temperature = 65 [C]
T1 = initial temperature = 30 [C]
Now replacing:
Q = 0.5*4.190*(65 - 30)
Q = 67.04 [J]
