A ball is kicked straight up from the ground with a speed of 10.0 m/s. How long will the
ball be in the air?
Answers
The total amount of time the ball would be in the air is 2.04 secs
To determine how long the ball will be in the air,
We will the equation for calculating total time of flight, T
For a projectile motion, the total time of flight of an object is given by
[tex]T = \frac{2usin\theta}{g}[/tex]
Where T is the total time of flight
u is the velocity of projection
θ is the angle of projection
and g is the acceleration due to gravity
From the question,
u = 10.0 m/s
θ = 90° (This is because the ball is kicked straight up)
Put these values into the equation,
[tex]T = \frac{2usin\theta}{g}[/tex]
[tex]T = \frac{2\times 10.0 \ sin90}{9.8}[/tex]
(NOTE: g = 9.8 m/s²)
∴ [tex]T = \frac{2\times 10.0 \times 1}{9.8}[/tex]
[tex]T = \frac{20}{9.8}[/tex]
T = 2.04 secs
Hence, the total amount of time the ball would be in the air is 2.04 secs

How much energy is required to take 500g of ice at -40 degrees to water at room temperature (22 degrees Celsius)? Show work pls
Answers
Answer: Given that:
Mass (m) = 20 g = 0.02 Kg,
temperature (T₁) = -10°C = -10+273 = 263 K
temperature (T₂) = 10°C = 10+273 = 283 K
Specific heat of water (Cp) = 4.187 KJ/Kg k
We know that Heat transfer (Q) = m. Cp.( T₂ - T₁)
= 0.02 × 4.187 × (283-263)
Q = 1.67 KJ
Heat transferred is 1.67 KJ

The pressure due to water at the bottom of the tank is 200000 Pascal.
What is pressure?It is the ratio between the force being applied and the surface area being applied to. The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure.
Given parameters:
Depth of the tank = 25 meter.
Depth of water in the tank: d = 25×4/5 meter = 20 meter.
Density of water: ρ = 1000 kg/m³.
Acceleration due to gravity: g = 10 m/s².
Hence, the pressure due to water at the bottom of the tank
= depth of water (d) × density of water (ρ) × acceleration of the gravity (g)
= 20 meter × 1000 kg/m³ × 10 m/s²
= 200000 Newton/meter²
=200000 Pascal.
Hence, the pressure due to water at the bottom of the tank is 200000 Pascal.

If an astronaut pushes on a box in space, how many forces are involved in this interaction?
A. One
B. Two
C. Three
D. Four
Answers
Answer: B. two
Explanation:
There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
However, In the absence of any forces, no force is required to keep an object moving.
This seems like a simple question, but if you wanted to get technical it would in fact be two forces. As there is still a miniscule amount of gravity.

How many electrons have been removed from a positively charged electroscope if it has a net charge of 6x10-11?
pls help !!!
Answers
How much negative charge has been removed from a positively charged electroscope if it has a charge of 7.5x10-11C?
If C is Coulombs then, −1 C is equivalent to the charge of approximately 6.242×10^18 electrons.
You already gave the answer: -7.5x10–11C
It is like asking: What colour is my white horse?
Now if you want to know how many electrons have been removed, then multiplying the number of electrons in a coulomb by the coulombs you have, you get 4.6815 x 10^8 electrons. Which is almost the same answer as before.
3.7 x 10^8 electrons are removed from a positively charged electroscope.
The magnitude of charge carried by one electron is 1.602 x 10^-19 C
From the question, we can see that the net charge on the electroscope is 6 x 10^-11 C
Given that;
6 x 10^-11 = 1.602 x 10^-19 n
Where n is the number of electrons removed from a positively charged electroscope
Therefore;
n = 6 x 10^-11/ 1.602 x 10^-19
n = 3.7 x 10^8 electrons

Answers
Answer:
A. 0.67 m/s² forward
Explanation:
F applied = 250 N
Fsin30 = 250/2 = 125N
F friction= 95 N
Fnet = F app - F fri
= 125-95
= 30 N ( forward)
Fnet = m a
30 = 45 a
a= 30/45
=2/3
= 0.67 m/s² (forward)
a ball is thrown at an original speed of 8.0 m/s at an angle of 35° above the horizontal. if there is no air resistance, what is the speed of the ball when it returns to the same horizontal level?
Answers
The speed of the ball when it returns to the same horizontal level is 8 m/s.
The given parameters;
initial speed of the ball, u = 8 m/sangle of projection, θ = 35⁰During the motion of a projectile, the speed of the projectile reduces as the projectile moves upwards and eventually becomes zero at the maximum height.
As the projectile moves downwards, the speed of the projectile starts to increase and it will become maximum (equal to the initial speed) before the projectile hits the ground.
Thus, we can conclude that the speed of the ball when it returns to the same horizontal level is 8 m/s.

there are 22 massive, positively charged, fundamental particles in the element's nucleus. Given this, the element is unquestionably titanium.
The nucleus of titanium contains 46 particles in total in which 22 protons and 26 neutrons.
What is atomic nucleus?The atomic nucleus can be described as the small and dense region containing of protons and neutrons at the center of an atom. An atom is made of a positively charged nucleus, with electrons surrounding it, bound together by electrostatic force.
Almost all of the mass of an atom is concentrated in the nucleus as the mass of electrons is negligible. Neutrons and Protons are bound together to create a nucleus by the nuclear force.
The diameter of the nucleus is about 1.70 fm for hydrogen to about 11.7 fm for uranium. Protons and neutrons are fermions, are the particles present inside the nucleus.
The titanium has 22 protons and 26 neutrons in its nucleus so it has 46 particles in its atomic nucleus.
