Stone is dropped from the edge of a roof, and hits the ground with a velocity of -165 feet per second. 165 feet high is the roof.
Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time (for example, 60 km/h northbound). In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea. A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined. Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI (metric system). In contrast to "5 meters per second east," which is a vector, "5 meters per second," for instance, is a scalar. In order to stress the difference between the instantaneous velocity and average velocity, velocity is defined as the rate of change of location with regard to time. The average velocity of an object, or the constant velocity that would produce the same resultant displacement as a variable velocity in the same time interval, v(t), over some time period t, may be required in various applications.

determine the minimum value of the coefficient of static friction which will prevent the blocks from moving in a pulley system
The minimum value of the coefficient of static friction which will prevent the blocks from moving in a pulley system is Fs=μsFN.
Create an inclination plane out of one of the materials, then place a body made of the other material on it to determine the minimum coefficient of static friction between the two. Up until the body begins to slide, steepen the incline. The coefficient of friction is the angle's tangent. A force that opposes motion is friction. Both static and kinetic friction work to keep a body at rest and to slow down its motion once it is moving. The normal force (FN), also known as the force produced perpendicularly by a body against the surface along which it is traveling, is proportional to the force generated by static friction (Fs). Fs=μsFN.
The properties of the two surfaces that are in contact with one another affect this coefficient.

a catapult launches a rock at a angle with respect to the horizontal. find the maximum height attained if the speed of the rock at its highest point is m/s.
The maximum height is 15.3m
The speed of the rock is -9.8m/s
Solution:
v(horizontal) = v0 cos 30 = 30
v0=30/cos30=34.6m/s
Therefore the initial vertical velocity is v0 sin30 =
34.6 sin30=17.3m/s
if the initial vertical speed is 17.3m/s, we can use
vfy^2=v0y^2+2ad
vfy = final y velocity=y vel at max height =0
v0y = initial y velocity = 17.3 m/s
a = accel = -9.8m/s/s
d = height
0 = 17.3^2-2(9.8)d
d = 17.3^2/19.6 = 15.3 m

The time period of pendulum on mars is 4.16 s.
A pendulum is a machine in which a point mass is hung from fixed support by an inextensible string. The length of the simple pendulum is the vertical distance between the point of suspension and the suspended body's centre of mass.
We know that, the time period of pendulum is inversely proportional to the square root of acceleration due to gravity.

Given that, T₁ = 2.5 s
g₂ / g₁ = 0.37
Placing the values in the above equation,
2.5/ T₂ = √ 0.37
2.5² = T₂² * 0.37
T₂² = 2.5² / 0.37

what direct evidence do we have that the weak and electromagnetic forces were once unified as a single electroweak force?
Answer:
There is direct evidence that the weak and electromagnetic forces were once unified as a single electroweak force from the study of subatomic particles.
Explanation:
The discovery of the W and Z bosons, which are particles that mediate the weak nuclear force, provided strong evidence that the weak force was once part of a larger electroweak force. The fact that the W and Z bosons have electric charge, and that their masses are related to the masses of the photon (the particle that mediates the electromagnetic force), supports the idea that the weak and electromagnetic forces were once part of a single electroweak force. Additionally, the mathematical symmetry of the electroweak theory, which unifies the weak and electromagnetic forces, provides further evidence for this theory.

the first students launches the ball with a velocity of 11.2 m/s in the x direction and 6.9 m/s in the y direction. what is the time the football takes to complete its flight path?
The time the football takes to complete its flight path is 1.04 sec.
Velocity is the directional pace of an item in motion as an indication of its rate of exchange in the role as determined from a selected frame of reference and as measured by way of a selected standard of time.
Average velocity is calculated by means of dividing your displacement (a vector pointing out of your initial role in your final position) through the entire time; the average pace is calculated by way of dividing the overall distance you traveled by means of the total time.
Calculation:-
Time of flight depends on the y direction
V in y direction is = 6.9 m/s
V² = U² - 2gh
h = u²/2g
= 47.61 /2 * 9.8
= 2.43 m
Time of flight = 2U/g
= 2 * 6.9 / 9.8
= 1.4 second.

atp is considered a high-energy molecule. when atp undergoes hydrolysis to adp, how much energy is produced?
a. 7.3 kcal/mole is required
b. 14.6 kcal/mole is released
c. 7.3 kcal/mole is released
d. 21.9 kcal/mol is released
The molecule ATP is regarded as having great energy. Energy is generated at a rate of 7.3 kcal/mol during the hydrolysis of ATP to ADP.
To keep the cell running continually, ATP must be replenished. Normally, ATP is present in cells in concentrations of 1 to 10 uM.
Describe hydrolysis.
When chemicals and water interact chemically, the result is hydrolysis, which decomposes both the material and the water.
Reactions involving salts, carbohydrates, proteins, lipids, etc. can undergo hydrolysis.
In catabolic processes, organic materials are typically hydrolyzed with the aid of enzymes.
Polysaccharides are broken down into monosaccharides, glycerol and fatty acids into lipids, and amino acids into proteins.
Hydrolysis is regarded as a crucial phase in the breakdown of silicate and aluminosilicate glasses, ceramics, and minerals because it destroys the bond network in silicates.

the planets that are farthest from the sun are the largest bodies in the solar system, but have the lowest average densities. which is the best explanation for this arrangement of the planets?
The temperatures on the Jovian planets were low enough to for the buildup of ice, which resulted in planets with massive sizes.
The largest planets in the solar system are also the ones with the lowest average densities because they are the ones closest to the sun. The larger gas and ice giants have a tendency to form further from the Sun because the regions closer to the Sun are too warm for the lighter gases to condense there. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are in order of proximity to the sun. Pluto, which was once thought to be the outermost planet, is now categorized as a dwarf planet. Pluto is not the only dwarf planet that has been found farther from the Sun. Out of all the planets in our solar system, Saturn has the lowest density. Saturn would float in a large enough body of water because it is less dense than water. But Saturn's mass is over 95 times greater than that of the Earth.
