Answer:
Speed is 1.962*10^-3m/s
Explanation:
Given that
Mass of proton==1.67*10^-27
Acceleration due to gravity (g)=9.81m/s^2
Angle of inclination A=90°
Charge (q)=1.6*10^-19
Magnetic field (B)=5*10^-5T
From lorentz force
It can be seen that
F=w =mg=qvBsinA
We're Velocity (v)=mg /qBsinA
V=1.67*10-27*9.81/1.6*10^-19*5*10^-5*sin90
V=1.962*10^-3m/s
Using the Definition of Kinetic Energy, we have:
Answer:
The correct option is (a).
Explanation:
Given that,
The energy of photon, E = 2.52 eV
We need to find the wavelength of the photon in nm. The formula for the energy of a photon is given by :
The nearest option is a) i.e. 492.34127 nm.
There are six skill-related fitness components: agility, balance, coordination<span>, </span>speed<span>, power, and reaction time. Skilled athletes typically excel in all six areas. Agility is the ability to change and control the direction and position of the body while maintaining a constant, rapid motion.</span>
Answer:
Mass is the same, weight is less.
Explanation:
We know the following equation
W = mg
where m is the mass of the astronaut which is constant and W is the weight. As g (the acceleration due to gravity) is a variable which it is directly proportional to the W, if g is lower on the Moon than on Earth, then W is lower on the Moon than on Earth.
