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.

You hold glider AA of mass 0.125 kgkg and glider BB of mass 0.375 kgkg at rest on an air track with a compressed spring of negli
andrew11 [14]

Answer:

The magnitude of the velocity of glider B is 0.2m/s and the direction is the negative direction  

Explanation:

Inelastic Collision

Given data

mass of glider A m1= 0.125kg

initial velocity u1=0

final velocity v1= 0.600 m/s

mass of glider B m2= 0.375kg

initial velocity u2=0

final velocity v2=?

We know that the expression for the conservation of momentum is given as

m1u1+m2u2=m1v1+m2v2

since u1=u2=u=0m/s

u(m1+m2)=m1v1+m2v2

substituting we have

0(0.125+0.0375)=0.125*0.6+0.375*v2

0=0.075+0.375v2

0.375v2=-0.075

v2=-0.075/0.375

v2=-0.2m/s

 The magnitude of the velocity of glider B is 0.2m/s and the direction is the negative direction

vfiekz [6]

Answer:

The liquid formed from a melted solid has the same mass as the solid has.

Explanation:

As long as no water can escape, the mass of the ice before melting must equal the mass of the liquid water after.
