Answer:
F = 12.5N
Explanation:
Force (F) = Mass (m) x Acceleration (a)
F = ma
F = (2.5kg) x (5m/s^2)
F = 12.5N
Magnetic field is produced by the magnet which will flow through any attractive item or even substance such as ferrofluid. Happy I could help:)
Y, bc the height of the bounce back is higher than x
a) Proton-proton: high repulsive electrostatic, very high attractive nuclear force. Proton-neutron: no electrostatic forces since neutrons are not charge carriers, high attractive nuclear force. Neutron-neutron: no electrostatic force for the same reason and huge attractive nuclear force.
b) There are two types of forces in the nuclei: repulsive electrostatic and attractive nuclear. Nuclear act between all nucleons, electrostatic only between protons. To make a nucleus stronger, increase number of attractive forces by increasing amount of neutrons.
c) Cause due to equivalence between mass and energy E=mc^2 change in energy (which happens in nuclear reaction) causes on change in mass. Starting mass just converts to energy, that's why it's greater than the ending mass.
There's no benefit from being stressed out, my lord.
x = 8 cos(3t + π/3)
When t=0, x = 8 cos(π/3)
Position = 8 cos(π/3) = 8 (0.5) = 4 .
Speed = first derivative of 8 cos(3t + π/3) =
- (8) (3) sin(3t + π/3) = - 24 sin(π/3) = -20.78
Acceleration = second derivative of 8 cos(3t + π/3)
= first derivative of - 24 sin(3t + π/3)
= - (24) (3) cos(3t + π/3)
= -72 cos(π/3) = -36 .
The period of the motion is the period of cos(3t + π/3) .
That's the same as the period of cos(3t) .
When is the first time after (3t=0) when (3t=2π) ? It's t = 2π/3 .
The period is 2π/3 .
The amplitude of the motion is the amplitude of 8 cos(.....) .
The amplitude of the cosine is 1 .
The amplitude of 8cos(...) is 8 .
Words cannot express my boundless gratitude
for the generous gift of your 5 points, my lord.
A full 1 point per answer !
The warm cloudy water and green bread-crust are delicious too.
