The maximum height reached by the ball during the upward motion is 24.7 m.
The given parameters;
initial velocity of the ball, u = 22 m/sThe maximum height reached by the ball is determined using the third kinematic equation as shown below;
v² = u² - 2gh
where;
v is the final velocity of the ball at the maximum height = 0h is the maximum height attained by the ball0 = u² - 2gh
2gh = u²
[tex]h = \frac{u^2}{2g} \\\\h = \frac{22^2}{2(9.8)} \\\\h = 24.7 \ m[/tex]
Thus, the maximum height reached by the ball during the upward motion is 24.7 m.

When you describe a liquid as thick, are you saying that it has a high or a low viscosity?
The liquid with greater thickness will be more viscous since it flow speed is lower. Therefore, the more thick liquids is more viscous and flow slowly.
What is viscosity ?Viscosity of a liquid is the resistance to its flow. Viscosity depends on the density and thickness of the liquid. The more thicker the liquid the more viscous it will be.
Less thick liquids will flow fastly. For example water is a less viscous liquid as we see it flow so quickly. Whereas, honey, oil, etc are more viscous and the mobility of their liquid particles are resisted by viscosity.
The more viscous liquids generally has higher specific heat capacity as in the case of water and oil. The particle - particle attractive force is higher in highly viscous liquids.

a tennis ball is launched from the floor at a velocity of 90 m/a at an angle of 13 degrees to the horizontal. calculate its range
Answer:
~186
Explanation:
1) R= (V^2 × sin A ) /g
V=90 m/a
A= 13°
g= 9.8 or 10 (I will take 9.8 for right result)
R= (90^2 × sin 13) / 9.8 = 185.928932672 ~ 186

This electric force calculator will enable you to determine the repulsive or attractive force between two static charged particles. Continue reading to get a better understanding of Coulomb's law, the conditions of its validity, and the physical interpretation of the obtained result.
How to use Coulomb's law
Coulomb's law, otherwise known as Coulomb's inverse-square law, describes the electrostatic force acting between two charges. The force acts along the shortest line that joins the charges. It is repulsive if both charges have the same sign and attractive if they have opposite signs.
Coulomb's law is formulated as follows:
F = keq₁q₂/r²
where:
F is the electrostatic force between charges (in Newtons),
q₁ is the magnitude of the first charge (in Coulombs),
q₂ is the magnitude of the second charge (in Coulombs),
r is the shortest distance between the charges (in m),
ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N·m²/C². This value is already embedded in the calculator - you don't have to remember it :)

white light such as that from the sun is actually only ultraviolet light.?
Answer:
no
Explanation:
White light, which is the visible light, from the sun contains all the rainbow colors; however, ultraviolet is a radiation emitted from the sun and it is nonvisible to humans.
No white light and ultraviolet light are the two types of radiation coming from the sun.
What are solar radiations?The light coming from the sun contains different types of radiation that travel at different wavelengths this radiation is called solar radiation.
Types of solar radiation are visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Due to this visible light, we can see on earth because it has the frequency that our eyes can see.
visible light contains seven colors that are at different wavelengths. So when the diffraction of visible light takes place we can see these seven colors.
Thus white light and ultraviolet light are the two types of radiation coming from the sun.

what is the angular speed of the tip of the minute hand on a clock, in rad/s?
Answer:
0.10472 radians/minute
Explanation:
It completes a full rotation around that circular clock in 60 minutes. So the angular speed of the minute hand is 2 * pi / 60 = pi / 30 = 0.10472- radians/minute .
The angular speed is the ratio of angular displacement to time. Then the angular speed is π/1800 radians per second.
What is angular speed?The rate of change of angular displacement is called angular speed.
We know that the angular speed formula
[tex]\rm Angular \ speed = \dfrac{Angular \ displacement }{time}[/tex]
The angular speed of the tip of the minute hand on a clock, in rad/s, will be given as
We know that in one hour it rotates 360 degrees or 2π. And in one hour we have 3600 seconds. Then the angular speed will be
[tex]\rm Angular \ speed = \dfrac{2\pi}{3600}\\\\\\Angular \ speed = \dfrac{\pi}{1800}[/tex]

Distance between gas molecules in the case of:
-Increase in temperature
-Decrease in temperature
-Increase in volume
-Decrease in volume
-Increase in pressure
-Decrease in pressure
Answer:
-Increase in temperature: increase
-Decrease in temperature: decrease
-Increase in volume: increase
-Decrease in volume: decrease
-Increase in pressure: increase
-Decrease in pressure: decrease
Explanation:
-Increase in temperature:
● Molecules gain kinetic energy and move fast thus increasing distance
-Decrease in temperature:
● Kinetic energy of molecules decrease so they have smaller distance
-Increase in volume:
● Molecules have more space to move around so distance increase
-Decrease in volume:
● Less space, molecules collide with each other because of decreased distance thus increasing pressure
-Increase in pressure
● Molecules collide with each other and the walls of container increasing pressure so molecules move faster and it increases distance
-Decrease in pressure:
● Molecules collide with each other and walls of container less frequently so distance between molecules decrease

The weight of the stone is 10N.
To find the weight of the stone, we need to know about the gravitational force on any object due to earth.
What is gravitational force?Gravitational force is a attractive force that arises between any two objects. The objects, on the earth surface or near the earth surface, experience the gravitational force of earth. This gravitational force is Known as the weight of the object. How can we calculate the gravitational force or the weight of an object, when it's near the earth surface?When an object is near the earth surface, its weight is mass × gravitational acceleration (g).
So, the weight of the stone= 1kg × 10 m/s²
= 10 N
Thus, we can conclude that the weight of the stone 100 m above a gorge is 10N.
