Answer:
Gemini
Explanation:
Zodiac Constellation or Sun sign is the constellation in which the Sun resides on the date of birth of a person. Throughout the year the Sun crosses across 12 constellations thus there are 12 Sun-signs. Though astronomically the Sun crosses across 13 constellations so there should be 13 zodiacs but most of the astrologers do not accept this. On the date of June 20, the Sagittarius which is a summer constellation and a zodiac can be seen high up in the sky in the night time. At this time the Sun will be in a constellation which is almost opposite to Sagittarius in the celestial sphere. That constellation is Gemini. Thus for a person born on 20 June, zodiac will be Gemini.
Answer:
80×5×10=4000J
so therefore, work done on the body is 4000J
Answer: the first shows the speakers actions; the second shows the beloveds opposition to them
Explanation:
Answer:
3.27 turns
Explanation:
To find how many turns (θ) will the stone make before coming to rest we will use the following equation:
Where:
: is the final angular velocity = 0
: is the initial angular velocity = 71.150 rpm
α: is the angular acceleration
First, we need to calculate the angular acceleration (α). To do that, we can use the following equation:
Where:
I: is the moment of inertia for the disk
τ: is the torque
The moment of inertia is:
Where:
m: is the mass of the disk = 105.00 kg
r: is the radius of the disk = 0.297 m
Now, the torque is equal to:
Where:
F: is the applied force = 46.650 N
μ: is the kinetic coefficient of friction = 0.451
The minus sign is because the friction force is acting opposite to motion of grindstone.
Having the moment of inertia and the torque, we can find the angular acceleration:
Finally, we can find the number of turns that the stone will make before coming to rest:
I hope it helps you!
G = 6.67 x 10-11 Nm2/kg2
a. Calculate the value of the gravitational force between an electron (mass = 9.11 x 10-31 kg) and a proton (mass is 1836 times greater than the mass of an electron) if the two particles are separated by 3.602 nanometers. (1 nanometer or 1 nm = 1 x 10-9 m)
F= ______ N
b. The force created in the above question is:
1. repulsive
2. attractive
Answer:
a.
b.Attractive
Explanation:
We are given that
Mass of an electron,
Mass of proton,
Distance between electron and proton,R=
a.Substitute the values then we get
b.We know that like charges repel to each other and unlike charges attract to each other.
Proton and electron are unlike charges therefore, the force between proton and electron is attractive.
Answer:
The answer is 9 m.
Explanation:
Using the kinematic equation for an object in free fall:
In this case:
Plugging those values into the previous equation:
The negative sign is because the reference taken. If I see everything from the rescuer point of view.
The final temperature of an ideal monatomic gas with an initial temperature of 128°C. is 114.53°C.
From the first law of thermodynamics,
ΔU=Q - W
Where,
ΔU - change in internal energy
Q - energy absorbed
W - work
So,
ΔU = 1180 J - 2020 J
ΔU = -840 J
From ideal gas law
Where, T2 is the final temperature,
n- moles of gas
R - gas constant
T1 - initial temperature,
Put the values in the equation
Therefore, the final temperature of an ideal monatomic gas with an initial temperature of 128°C. is 114.53°C.
