Answer:
Explanation:
Given
velocity of mug with which it leaves the bar is 1.7 m/s
Also
height of bar=1 m
Considering motion in vertical direction
here
t=0.451 s
so horizontal distance traveled is
here a=0
speed of mug will be combination of horizontal and vertical velocity
thus
for direction
is with x axis in clockwise sense
The characteristic of epithelial cells that makes them ideal for providing this type of protection is that the cells are packed tightly together.
Skin, the body's largest organ,is our first and best defense against external aggressors. The many layers work hard to protect us, however when its condition is compromised, its ability to work as an effective barrier is impaired.
Answer:
A beta emission(negatron)
Explanation:
1. A negatron resembles an orbital electron. It is represented as β⁻.
A negatron has a mass number of 0 but with a charge of -1
The decay of C-14 to N-14 can be depicted below:
¹⁴₆C → ¹⁴₇N + ₋₁⁰e
Both the mass number and atomic number is balanced according to the reaction.
2. In an electric field, the emission produced would be deflected towards the positive pole because it is negatively charged.
Answer:
(A) The distance of the center of Planet X is m
(B) The speed of the satellite is
Explanation:
Given:
Mass of the planet kg
Time period days sec
(A)
From kepler's third law
Where
Now for finding the distance of planet X,
m
(B)
Speed of the satellite is given by,
Therefore, the speed of planet is
Nuclear binding energy is necessary to overcome EINSTEIN'S MASS DEFECT. Nuclear binding energy refers to the energy required to separate an atomic nucleus into its constituent elements, that is protons and electrons. The mass of a nucleus is always less than the sum of all its constituents. The difference is a measure of the nuclear binding energy which holds the nucleus together and it is called mass defect and can be calculated for using Einstein's formula for mass defect.
