Which form of emission is commonly not written in nuclear equations because they do not affect charges, atomic numbers, or mass numbers?
Answer:
Gamma radiation .
Explanation:
Three types of emission result at the time of nuclear emission .
alpha emission
Beta emission
Gamma radiation emission
Gamma radiation results in the emission of gamma ray . This is a very high frequency radiation . It is not a particle having charge and mass like alpha and beta emission . So it has no effect on the mass and charge of the product that is formed after gamma radiation . The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product . It causes negligible change in the mass of the product and no change in the charge of the product.
That is why , generally this product is not written in the nuclear reaction .
Answer:
The answer is Gamma ray
Explanation:
Because this is a very high frequency radiation, is not a particle having charge and mass like alpha and beta emission, so it has no effect on the mass and charge of the product that is formed after gamma radiation. The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product, it causes negligible change in the mass of the product and no change in the charge of the product.

(Choice A) A Cytosol
(Choice B) B Cell membrane
(Choice C) C Ribosome
(Choice D) D Cell wall
Answer: A Cytosol
Explanation: Jelly - like fluid that fills the space between cell organelles. Hoped This Helped :) Have a blessed day.
The cytoskeleton, which gives a cell its structure, allows organelles to move inside the cell, and provides a method by which the cell itself can move, is an ordered framework of fibrous molecules found in the cytoplasm. Thus, option A is correct.
What is the main function of cytosol in the cell?The fluid that fills cells is called cytosol. In this water-based solution, organelles, proteins, and other cell components float. Any cell's cytosol is a sophisticated solution whose characteristics allow for the performance of life's essential processes.
The cytoplasm houses all the organelles found in eukaryotic cells, including the nucleus, endoplasmic reticulum, and mitochondria.The portion of the cytoplasm that is not contained in an organelle is known as the cytosol.
Therefore, Although the cytoplasm may not seem to have any shape or organization, it is actually quite well-organized.

The net external force on the propeller of a 3.32 kg model airplane is 23 N forward. What is the acceleration of the airplane?
Answer:
6.93 m/s^2
Explanation:
Given that the The net external force on the propeller of a 3.32 kg model airplane is 23 N forward
Where
Mass M = 3.32kg
Force F = 23 N
Force = mass × acceleration
Substitute all the parameters into the formula
23 = 3.32 × a
a = 23/3.32
a = 6.93 m/s^2
Therefore, the acceleration of the airplane is 6.93 m/s^2
The Flash can travel 400 m in just 5.2 minutes. What is his average velocity in m/s?
Answer:
76.9231
Explanation:
Divide 400m by 5.2 to get the answer.
Speed = (distance) / (time to cover the distance)
Speed = (400 m) / (5.2 minutes)
Speed = (400 m) / (312 seconds)
Speed = 1.28 m/s
There's not enough given information to find his velocity.
(I'll be honest with ya, Flash: 1.28 m/s is no big deal. It's only about 2.87 miles per hour. My dog can walk faster than that, and so can most healthy people. If that's the best you can do, then you probably shouldn't be running around chasing bad guys.)
2. Find the velocity when the displacement is 40 m and the time is 5 s.
Answer:

What is the average speed of a car that traveled 222.0 miles in 4.596 hours?
Answer:
48.3mph
Explanation:
Given that
Distance = 222.0miles
Time = 4.596hours
Average speed = total distance/total time
= 222.0miles/4.596
= 48.3mph
Hence the average speed is 48.3mph

Which cell structure is thought to have arisen through an endosymbiosis in plant but not animal cells?
Choose 1 answer:
(Choice A) A Cell wall
(Choice B) B Mitochondria
(Choice C) C Chloroplast
(Choice D) D Ribosome
Answer:
chloroplast
Explanation:
Endosymbiosis theory explains the origin of chloroplast and mitochondria in the eukaryotic organisms.
When the pro-eukaryotes engulfed the blue-green algae or photosynthetic bacteria, these bacteria formed the symbiotic relationship with the pro-eukaryotes. These photosynthetic bacteria transformed into the chloroplast organelles of the eukaryotes which can capture the sunlight and use it in the synthesis of glucose molecules. These eukaryotic cells later formed the plant kingdom.

Answer:
1:25
Explanation:
The force acting on an object is given by :
F = ma ...(1)
m is mass and a is acceleration
It is given that the ratio of force acting on the bus and car 25:1 i.e. [tex]\dfrac{F_1}{F_2}=\dfrac{25}{1}[/tex], 1 is for bus and 2 is for car.
We need to find the ratio of the acceleration produced in the car to the acceleration produced in the bus. From equation (1),
[tex]\dfrac{F_1}{F_2}=\dfrac{a_1}{a_2}[/tex]
[tex]\dfrac{a_2}{a_1}=?[/tex]
[tex]\dfrac{F_1}{F_2}=\dfrac{1}{25}[/tex]
So, the ratio is 1:25.

How do you think the mass of an object affects how much friction get exerted on the object by a rough surface?
Explanation:
Friction can't affect mass of a substance(considering for a substance whose mass doesn't change with time),rather it is the mass of an object which can affect friction variously. Let's take some example to understand the situation. So,higher the mass of the object,higher will be the frictional force.
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
Driving at 75 m/s, you hit the brakes on your new car, accelerating at
a rate of -20 m/s2. How much time will it take the car to come to
rest?
Explanation:
initial velocity, u = 75m/s
acceleration, a = -20m/s2
final velocity, v = 0m/s (rest)
Using the formula,
v = u + at
0 = 75 + (-20)t
t = 3.75 seconds

The average acceleration of the motorcycle is determined as 3 m/s².
Acceleration of the motorcycle
The acceleration of the motorcycle is calculated as follows;
a = (v - u)/t
where;
v is the final velocityu is the initial velocityt is time of motiona = (15 - 6)/3
a = 3 m/s²
