The answer will be neutral because the same number of protons and the same number of electrons
Heat energy required to increase the temperature of water in bathtub is 12,546,000 Joules.
<h3>What is thermal energy?</h3>
The energy contained by an object by virtue of heating is known as thermal energy.
Given is the mass of water m = 150 kg, Temperature change ΔT = (40 -20)= 20 °C
The specific heat of water Cp =4182 J/kg.°C
Heat transfer Q =m x Cp x ΔT
Q = 150 x 4182 x 20
Q = 12,546,000 J
Thus, Heat energy required to increase the temperature of water in bathtub is 12,546,000 Joules.

the first bump car will move
Explanation:
this is because as long as the other bumper car is coming with force, it mass changes and then , it is able to push the other one
Answer:
BC =980nm
Explanation:
Given wavelength =490nm
m=2
Required to find (OB - OC) = BC (more distant slit - nearest slit ) = dsin theta
We have dsin theta = m*wavelength
or BC = m* wavelength = 2*490nm
= 980nm = 98.000A
