Answer:
The mass of object is calculated as 5.36 kg
Explanation:
The known terms to find the mass are:
acceleration of object (a) = 22.35 
Force exerted (F) = 120N
mass of an object (m) = ?
From Newton's second law of motion;
F = ma
or, 120 = m × 22.35
or, m= 
kg
∴ m = 5.36 kg
Answer:
K.E = 1.28 × 10^-17 KeV
Explanation:
Given that a particle accelerator at CERN can accelerate an electron through a potentialdifference of 80 kilovolts.
To Calculate the kinetic energy (in keV) of the electron, let us first find the electron charge which is 1.60 × 10^-19C
The kinetic energy = work done
K.E = e × kV
Substitute e and the voltage into the formula
K.E = 1.60 × 10^-19 × 80
K.E = 1.28 × 10^-17 KeV
Therefore, the kinetic energy is approximately equal to 1.28 × 10^-17 KeV
Explanation:
there are many things. I am not sure what your teacher told you.
one of the first strange observations leading to this conclusion was the "loop-di-loop" in the track of Mars. because of the different orbits of Earth and Mars, sometimes one (particularly Earth as the faster one) swings around the sun in relation to the other, and with that first moves away and suddenly moves closer again, making the track of Mars appear on Earth as if it would make a loop in the sky.
Answer:
The angle of incidence is equal to the angle of reflection.
Explanation:
yes.
