<span>we know energy = power*time(in hour) so energy used by 1.20kw(1200 watt) toast oven used for 6.2 min(6.2/60 hour) = 1200*(6.2/60)=1200*0.103 = 124 watt hour. Energy used by 11 w cfl used for 8.50 hour = (11*8) + (11* (50/60)) = 88+9.166=97.166 watt hour.</span>

8. As you throw a 2.00 x 102 g baseball, your hand moves a distance of 80.0 cm before you release the ball. If you exert an aver
olga nikolaevna [1]

Answer:

v = 21.0 m / s

Explanation:

In this exercise, it is generally asked to determine the final speed of the ball.

Let's start by finding the acceleration of it

            F = ma

            a = F / m

let's reduce the magnitudes to the SI system

            m = 2.00 102 g (1kg / 1000g) = 0.200 kg

            x = 80.0 cm (1m / 100 cm) = 0.800 m

we calculate

            a = 55.0 / 0.200

            a = 275 m / s

now we can use kinematics, where the ball has an initial velocity of zero and travels a distance x = 80 cm with the force

            v² = v₀² + 2 a x

            v² = 0 + 2ax

            v = \sqrt{2ax}

let's calculate

           v = \sqrt{2 \ 275 \ 0.800}Ra 2 275 0.800

           v = 20.98 m / s

if we use the criteria of significant figures

           v = 21.0 m / s

What happens if balanced forces are applied to a moving object? A. The object stops moving. B. The object moves faster in the sa
Gemiola [76]

Answer:

The object keeps moving at the same speed and direction.

Explanation:

This is because the balanced forces acting on the object cancel out each other since the are in opposite directions, leaving only the original force acting on the object which is causing its motion.To illustrate, let F₁ be the initial force and F₂ and F₃ be the balanced forces. The net force F = F₁ + F₂ + F₃. Since F₂ and F₃ are balanced, F₂ = -F₃ ⇒ F₂ + F₃ = 0.

So,

F = F₁ + F₂ + F₃

  = F₁ + (F₂ + F₃)

  = F₁ + 0

  = F₁

Which is the original force acting on the object. Thus, the object keeps moving at the same speed and direction
