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.

A boy, standing at point O, is whirling a ball on a string over his head. After several whirls, he lets go of the string and the
Vikki [24]
When a ball is whirled using a string, it is restricted to move only in circular motion because the net force acting on the ball is towards the center of the circle. Hence, the acceleration of the ball is towards the center. But the velocity of ball is tangential to this circular path all the time. When the whirling is stropped, the string becomes slack and tension in the string becomes zero. The ball no more performs circular motion and the ball moves tangentially to the circle in straight line. Therefore, before letting go, velocity was variable. After letting go, velocity becomes constant.

Early cameras were little more than a box with a pinhole on the side opposite the film. (a) What angular resolution would you ex
ollegr [7]

Answer:

angular resolution = 0.07270° = 1.269 × 10^{-3} rad

greatest distance from the camera = 118.20 m = 0.118 km

Explanation:

given data

diameter = 0.50 mm = 0.5 × 10^{-3} m

distance apart = 15 cm =  15× 10^{-2} m

wavelength λ = 520 nm = 520 × 10^{-9} m

to find out

angular resolution and greatest distance from the camera

solution

first we expression here angular resolution that is

sin θ = \frac{1.22* \lambda }{D}   .......................1

put here value λ is wavelength and d is diameter

we get

sin θ = \frac{1.22*520*10^{-9}}{0.5*10^{-3}}

θ = 0.07270° = 1.269 × 10^{-3} rad

and

distance from camera is calculate here as

θ = \frac{I}{r}    .................2

I = \frac{15*10^{-2}}{1.269*10^{-3}}

I = 118.20 m = 0.118 km

What is the power involved in lifting a 1.0-kg object 1.0 m in 1.0 s??
MAVERICK [17]
Mass  = 1kg 
Distance  = 1m 
Time = 1s
Force= Mass x Acceleration due to graviy
          =  1 x 9.8 = 9.8
Velocity = Distance  / time
              = 1 / 1 =1m/s
Power = Force x velocity
           = 9.8 x 1 = 9.8 W

Someone help me please.
Soloha48 [4]

1/2*2.8*x^{2}=2.8*9.81*1.50

X=5.425

Because K.E=1/2*M*V² and it is equal to P.E in the conservation of energy which means its K.E=P.E

P.E=m*g*h

So K.E equals 1/2*2.8*(5.425)²=41.20
