Answer:
C. Protons have an electrical charge, but neutrons have no charge.
Explanation:
Protons and neutrons both are parts of nucleus and they stay inside the nucleus due to large nuclear force between them
Mass of proton and mass of neutron is almost same or in more precisely we can say that neutrons are slightly heavy than protons
mass of neutrons is 1.008 amu while mass of protons are 1.007 amu.
the main different between them is that protons are positively charged and their charge is same as that of charge of electron
while neutrons are electrically neutral and they do not have any charge on them.
so correct answer will be
C. Protons have an electrical charge, but neutrons have no charge.
Object's centripetal acceleration is 20 m/s^2
An object moving in a circular path with a constant speed, does have an acceleration, as it changes its direction as the object rotates. This centripetal acceleration can be found using below mentioned relation:
Ac(centripetal acceleration) = (v^2)/r; where, v is the constant speed of object and r is the radius of circular motion
Therefore, Ac = 10*10/5 = 20 m/s2
Answer:
Height of the cube under water will be 3.33 cm
Explanation:
We have given height of the cube = 5 cm
Density of the material
Density of liquid
We have to find the height of the cube under the water
Height under water is given by
Height under water =
Height of the cube under water will be 3.33 cm
