a) If an object has more mass than another object, it will accelerate_less____
b) In order to accelerate an object more, one would need to apply_more____ force.
c) If an equal force is applied to two different objects, the less massive object will accelerate_more___
The answer is less, more and more.
Relationship between mass and accelerationIf an object has more mass than another object, it will accelerate less. In order to accelerate an object more, one would need to apply more force. If an equal force is applied to two different objects, the less mass of an object will accelerate more
The acceleration of an object depends directly on the force acting upon the object, and inversely on the mass of the object.

Consider two future observatories in space. Observatory X consists of a single 50-meter telescope. Observatory Y is an interferometer consisting of five 10-meter telescopes, spread out over a region 100 meters across. Which observatory can detect dimmer stars, and which one can see more detail in its images
The size and aperture of the telescopes determine its ability to gather light
and reveal details.
A) Observatory X can detect dimmer stars and Observatory Y reveals more
details.
Reasons:
The benefits of using several small telescopes included the production
high resolution images of bright objects such as binary stars that reveal
more details similar to a telescope with a very large aperture, with a
process known as interferometry, through which a star's diameter can be
determined.
The benefit of a large telescope is its ability to gather light from a source,
thereby making possible to detect a dim light source, such as dimmer
stars.
Therefore;
The single large telescope in observatory X can detect dimmer stars while
the interferometer consisting of five 10-meter telescopes, spread out over a
region 100 meters across can see more detail in its images.
The correct option is; A) Observatory X can detect dimmer stars and
Observatory Y reveals more details.

What is the force of a 13kg ball that has been dropped and has fallen for 1 second?
Answer:
127.4 newtons
Explanation:
Assuming g = 9.8:
F = ma = 13(9.8) = 127.4 N
The force of a 13 Kilogram ball that has been dropped and has fallen for 1 second, then the force offered by the ball would be 127.53 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.
As given in the problem we have to find the force of a 13-kilogram ball that has been dropped and has fallen for 1 second,
The force of the dropped ball = mass of the ball × acceleration due to gravity
The force of the dropped ball = 13 × 9.81
= 127.53 Newtons
Thus , the force of a 13kg ball that has been dropped and has fallen for 1 second would be 127.53 Newtons.

water being turned into ice cubes in a freezer is an example of _____.
Answer:
an exothermic process and the change in enthalpy, ΔH, will be a negative number
Water is turned into ice cubes in a freezer is an example of an exothermic process.
What is an exothermic process?An exothermic process can be described as a thermodynamic process or reaction that releases energy from the system to its surroundings, usually in the form of heat, light, or sound.
While an endothermic process is an opposite of an exothermic process where the heat absorbs energy usually in the form of heat. In the physical sciences of chemical reactions, the chemical bond energy is changed into thermal energy (heat).
In exothermic reactions, the heat that is liberated by the reaction occurs the form of the kinetic energy of molecules. The transition of electrons from one energy level to another leads light to being released. This light is equal to the stabilization energy of the energy for chemical reaction.
The freezing of water is an exothermic process as the water becomes solid it releases energy to the surroundings.

Information travels at 120 metres per second in neurones. Calculate the time it would take for the information to travel 2.3 m along a neurone. Give your answer in milliseconds.
Answer:
5 remainder 5
Explanation:
divide 120 by 2.3
To calculate the time it would take for information to travel a certain distance along a neuron, you can use the formula: Time = Distance / Speed.
Given that the information travels at 120 meters per second and the distance is 2.3 meters:
Time = 2.3 m / 120 m/s
Time ≈ 0.019167 seconds
To convert seconds to milliseconds, multiply by 1000:
Time in milliseconds ≈ 0.019167 s * 1000 ms/s ≈ 19.167 ms
So, it would take approximately 19.167 milliseconds for the information to travel 2.3 meters along a neuron.

how to find the density of air?
The table contains the planets in our solar system in order of their average distance from the Sun and their corresponding diameters. The first step in creating a model of the solar system is to scale these large diameters into smaller, more manageable numbers. Eventually, we’ll represent these numbers using circles drawn on paper. MercuryVenusEarthMarsJupiterSaturnUranusNeptune Diameter (km)487912,10412,7566792142,984120,53651,11849,528 Scaled Diameter (cm) 3.51.9 The ratio between Earth’s actual diameter and its scaled diameter can be used to find the scaled diameter of the other planets. Earth’s diameter of 12,756 kilometers is scaled to 3.5 centimeters as shown in the table. Now let’s find the scaled diameter of Mars as an example. Using the calculations shown, Mars’s diameter of 6,792 would be scaled to 1.9 centimeters. d × 12,756 = 6,792 × 3.5 d = 1.9 cm Use this same process to complete the table with the scaled diameters of the other planets. Round each answer to the tenths place. If you need additional math help, visit the Proportions section of the Math Review.
The scaled diameters of the missing planets are listed below:
Mercury 1.4 cm
Venus 3.3 cm
Mars 1.9 cm
Jupiter 39.2 cm
Saturn 33.1 cm
Uranus 14.0 cm
Neptune 13.6 cm
How to determine the scaled diameters of a planet
In this question we must use conversion factor to calculate the scaled diameters by means of the following direct relationship:
d = k · D (1)
Where:
D - Real diameter, in kilometers.d - Scaled diameter, in centimeters.k - Conversion factor, in centimeters per kilometer.The conversion factor is found by using the real and scaled diameter of the Earth:
k = 3.5 cm/12,756 km
k = 7/25512 cm/km
Then, we determine the scaled diameters of the rest of planets:
Mercury 1.4 cm
Venus 3.3 cm
Mars 1.9 cm
Jupiter 39.2 cm
Saturn 33.1 cm
Uranus 14.0 cm
Neptune 13.6 cm
Remark
The statement reports a table with numerous mistakes, the correct table is shown below:
Planet Diameter (km) Scaled Diameter (cm)
