If a horse is running at a speed of 35 m/s when it's rider pulls up on the reigns. After 5 seconds the horse slows down to a pace of 15 m/s. What is the horse's rate of acceleration?
Answers
The acceleration of the horse's speed which is running at a speed of 35 m/s when it's rider pulls up on the reigns will be -4 m/s².
What is Acceleration?Acceleration can be defined as the rate of change of velocity with respect to time. Acceleration is a vector quantity as it has both the magnitude and direction. The SI unit of acceleration is m/s² or ms⁻².
The expression for acceleration will be:
a = (v-u)/ t
v = 15m/s,
u = 35m/s,
t = 5 sec,
a = (15-35)/ 5
a = -20/ 5
a = -4 m/s²
Therefore, there will a negative acceleration of 4 meters per second square.

Answers
Answer: For forces on flat rigid bodies such as a wall, it is less direct in the calculation of work done as force times distance or displacement compared to other situations. You will have to calculate the pressure exerted first which will be P = F/A, where F is the force as above in Newtons, and A is the area of the wall first. There should also be a pressure limit for the wall in question based on what it is composed of and its dimensions from structural mechanics. The exerted force must exceed the upper limit of tolerated force to break the wall. In any case even without breaking the wall, using very accurate optical technology you can estimate the displacement now a days however minute, or the change in the form of volume of displacement also due to the pressure. Here Work done can be given still as follows : W = F •d, or W = P •V, or W = (F/A)•V. Here V will be the approximate

X-Rays can reveal an objects temperature since temperature determines the wavelength of its radiation. The HOTTER the object, the BIGGER the wavelength is because if tempeture determines wavelength then the hotter it is the bigger the wavelength would be and vice versa.

Answer:Both types involve multiple atoms coming together to form a more complex structure.Both types of bonding result in atoms becoming more stable in the group than they were individually. Both types of bonding are exothermic as the potential energy of the participants is lowered as they form the bond. Ionic bonding occurs between atoms that have opposite needs for electrons (metals and nonmetals) and results in a transfer of electrons. Covalent bonding occurs between atoms that have similar needs for electrons (two nonmetals) and results in a sharing of electrons.
By transferring electrons, ionic bonding leads to the formation of charged particles that have either an excess of protons (cation) due to the loss of electrons or an excess of electrons (anion) due to the gain of electrons. Covalent compounds contain neutral atoms.The electrostatic attraction that occurs in ionic bonding is between cations and anions. The electrostatic attraction in covalent bonding arises from a shared electron’s attraction for its original nucleus as well as the nucleus of the sharing atom.
Ions bond in a pattern that maximizes attractions between oppositely charged ions and minimizes repulsions between like charged ions. The geometric pattern that arises is called the crystal lattice and is consistent throughout the crystal. All ions are held by a network of ionic bonds which are considered strong intramolecular forces. Atoms in a covalent compound are held together by covalent bonds which are also considered strong intramolecular forces. In the solid, crystalline state, both types lead to regular, ordered patterns and structures.
Both types of compounds can undergo changes in physical state under the right conditions of temperature and pressure.
Both types of compounds have a net neutral charge.
Both types of compounds contain a fixed ratio of participants that is represented by the subscripts in their chemical formulas (they do not require a 1:1 ratio).

PLEASE. A 20 kg box is being pulled across a floor by a horizontal rope. The tension in the rope is 99 Newtons. The coefficient of friction is 0.25. What is the force of friction on the box? What is the acceleration of the box?
Answers
Answer:
Force of Friction = -50 (N)
Acceleration = 2.45 (m/s^2)
Explanation:
Force of Friction = f = N * coefficient of friction
N = m * g
=> Force of Friction = m * g * coefficient of friction
f = 20 * 10 * -0.25 = -50 (N)
------------------------------------------------------
(1) F net = F + f
(2) F = m * a
(1) F net = 99 - 50 = 49
(2) a = 49 / 20 = 2.45 (m/s^2)

Which is a valid velocity reading for an object?
A.45 m/s
B. 45 m/s north
C. 0 m/s south
D. 0 m/s
Answers
The valid option would be 45 m/s north. This option specifies a velocity of 45 meters per second in the north direction. It includes both the magnitude (45 m/s) and the direction (north) of the velocity. Hence the correct option is (A).
A. 45 m/s: This indicates a velocity of 45 meters per second without specifying the direction. It represents the magnitude of the velocity but does not indicate a particular direction.
B. 45 m/s north: This indicates a velocity of 45 meters per second in the north direction. It specifies both the magnitude (45 m/s) and the direction (north).
C. 0 m/s south: This indicates a velocity of 0 meters per second in the south direction. No velocity. It specifies both the magnitude (0 m/s) and the direction (south).
D. 0 m/s: This indicates a velocity of 0 meters per second, meaning the object is not moving. It represents zero speed and zero direction.
The correct option is (A).
