Juggler will catch the second ball 1 second after catching the first ball as the first ball comes down 1 second earlier than the second.
Two balls are thrown into the air. The first ball goes up with a velocity of 9.8m/s and the second ball goes with a velocity of 14.7m/s. We have to find out the Time difference between the balls when both of them land in the hand. We have Newton's first equation : v = u + at => t = (v-u)/a
where, v = Final velocity, u = Initial velocity, a=g = Acceleration of gravity, and t = Time
For First ball, v1 = 9.8m/s, u1 = 0, g = 9.8 (acceleration for gravity), t1 = time and multiplying the equation by 2 for marking journey of balls for both going up and down
=> t1 = 2(v1-u1)/g => t1 = (9.8-0)/9.8
=> t1 = 2 seconds
For second ball, v2 = 14.7m/s, u2 = 0, g = 9.8 (acceleration for gravity),
t2 = time & multiplying the equation by 2 for marking journey of ball for both going up and down => t2 = 2(v2-u2)/g
=> t2 = (14.7-0)/9.8 => t2 = 3 seconds
Difference between the time taken by both balls t = t2-t1
=> t = 1 second
So the second ball lands after 1 second.

A motorcycle enters a freeway with a speed of 5.8 m/s and accelerates uniformly for 65 m in 7.2 s.
How fast is the car moving after this time?
The speed of the motorcycle is 9.02777m/s in 7.2 sec.
What is acceleration?The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration.
v(0) = 5.8
s(0)=0
s(7.2) = 65
s(t) =at^2/2 + v(0)t
s(7.2) = a(7.2)^2 + 5.8(7.2) = 65
a = (65-41.76)/51.84
a= 23.24/51.84 = about 0.4483 m/s²
v(t) = s'(t) = at +v(0) = at +5.8
v(7.2) = 0.4483(7.2) + 5.8

The value of spring constant for spring a and spring b is 531.70 and 52610.52 respectively. As the value of spring constant for Spring b is greater than a, So it is more stiffer.
What is spring constant?A spring's "spring constant" is a property that quantifies the relationship between the force acting on the spring and the displacement it produces. In other words, it characterizes a spring's stiffness and the extent of its range of motion.
a) For spring a,
Given, the extended length = 9.4cm = 0.094m
mass = 510 g = 0.51kg
For spring b,
The extended length = 0.95mm = 0.00095m
mass = 5.1 kg
The force acting on both springs will be -
For spring a,
F = mg (taking g = 9.8m/s²)
where m = mass and g = acceleration due to gravity
= 0.51 × 9.8
= 4.998N
Similarly, for spring b,
F = mg
= 5.1 × 9.8

The car in a time of 4 seconds will travel a distance of: 32 m
The formulas for uniformly varied rectilinear motion (UVRM) and procedures we will use to solve this exercise are:
a = (vf - vi) /tx = (vf²-vi²)/ (2a)Where:
x = distancevf = final velocityvi = initial velocitya = accelerationt= timeInformation about the problem:
vi = 16 m/svf= 0 m/st = 4 sa = ?x= ?Applying the acceleration formula we have:
a = (vf - vi) /t
a = (0 m/s - 16 m/s) /4 s
a = (-16 m/s) /4 s
a = -4 m/s²
Acceleration is negative because the car is decelerating
Applying the distance formula, we get:
x = (vf²-vi²)/ (2a)
x = [(0 m/s)²- (16 m/s)²]/ (2 * -4 m/s²)
x = (0 m²/s²- 256 m²/s²)/ -8 m/s²

Which statement belongs to Dalton’s atomic theory?
Atoms have a massive, positively charged center.
Atoms cannot be created or destroyed.
Atoms can be broken down into smaller pieces.
Electrons are located in energy levels outside of the nucleus.
The correct answer is Atoms cannot be created or destroyed.
Every element in space is made up of tiny, indivisible particles, which are invisible to the unaided eye, according to Dalton's atomic theory. These objects are referred to as atoms. Because "Atoms cannot be made nor destroyed by the human being," they are indestructible. The behaviour of an atom in one element differs from the behaviour of atoms in all other elements even though all the elements in an atom have the same mass.The leading philosophers of the day disagreed with Dalton's theory since it had some flaws. In that case, Aristotle fully disagreed, asserting that matter consisted of the four elements earth, wind, water, and fire. Scientists then adopted this view. The scientific community had now accepted atomic theory, but J. J. Thomson's finding in 1897 led to the next development. In his hypothesis, he described atoms as equally packed spheres of positively charged material that are filled with negatively charged electrons.

You have found that tides on earth are determined primarily by the position of the moon, with the sun playing only a secondary role. Why does the moon play a greater role in causing tides than the sun?.
You have found that tides on earth are determined primarily by the position of the moon, with the sun playing only a secondary role. The moon plays a greater role in causing tides than the sun because it is close to the earth than the sun.
Earth orbits around the sun due to its gravitational force, however, the formation of tides in the ocean takes place due to the force of gravity exerted by the moon.
Both the sun and the moon exert a gravitational pull on the earth.
Due to the difference in their distance, the moon plays a crucial role and has a dramatic effect on the earth which leads to tide generation as it has a greater force of gravity on earth as compared to the sun.
When the moon is closer to earth, a strong and large number of tides are formed.
In other words, no doubt the sun is much greater in size and has a large gravitational force but due to the large distance from earth, it does not play a greater role in the formation of tidal waves.

A star is moving directly towards earth at a large fraction of the speed of light. How does the light we observe from this star compare to the light received from the same star if it were at rest relative to earth?.
A star is moving directly toward earth at a large fraction of the speed of light. The light we observe from this star compared to the light received from the same star if it were at rest relative to earth will be blueshifted.
The elements of Earth are land, air, water, and life. Mountains, valleys, and flat places can all be found on the ground. Different gases, namely nitrogen and oxygen, make up the air. Rain, snow, ice, rivers, lakes, oceans, and streams are all examples of water. Doppler shift is the term used in physics to describe this phenomena, which is the alteration in wave frequency caused by an observer moving in respect to the source.
But much like the other planets, Earth is a planet that exists in space and is a part of the cosmos. It so happens that life exists here and that the conditions close to this planet's surface are favourable for life as we know it. The tiny, delicate planet Earth stands out in the universe.
