A sled with rider having a combined mass of 110 kg travels over the perfectly smooth icy hill shown in the accompanying figure. How far does the sled land from the foot of the cliff?

Answers

The sled land is "25.531 m" far from the foot of the cliff.

According to the question,

The velocity of the top = $V_t$

then,

→ $0.5 \ Vt^2-0.5 \ Vi^2 = -mgh$

→ $0.5 \ Vt^2 = 0.5 \ Vi^2- 9.8* 11$

→ $0.5 \ Vt^2 = 0.5 \ Vi^2- 107.8$

→ $=17.04 \ m/sec$

Now,

The projectile motion in horizontal direction,

→ $S_y = 11 = ut-0.5 \ gt^2$

$= 0-0.5* 9.8 \ t^2$

or,

→ $S_x = 17.04* 1.498$

$= 25.53 \ m$

Thus the above answer is the correct one.

Find the speed the sled has at the top of the hill from the law of conservation of mechanical energy. Equate the kinetic energy at the bottom of the hill to the kinetic plus potential energy at the top :

0.5mv₀² = 0.5mv² + mgh
v = √[v₀² - 2gh]
= √[(22.5m/s)² - (2 x 9.80m/s² x 11.0m)]
= 17.0m/s

From the time independent kinematics equation, find the vertical component of the sleds final velocity (note that the vertical component of the sleds initial velocity is zero) :

v² = v₀² + 2gΔy
= 0 + 2(-9.80m/s²)(-11.0m)
= -14.7m/s (select the neg root, because motion is downward)

With this you can find the time vertically which is the same horizontally :

v = v₀ + gt
t = (v - v₀) / g
= (-14.7m/s - 0) / -9.80m/s²
= 1.50s

Now, the horizontal distance is :

Δx = (v₀ + v)t / 2
= (17.0m/s + 17.0m/s)1.50s / 2
= 25.5m

According to modern atomic theory, it is nearly impossible to determine an electron’s exacta. color.
c. charge
b. position.
d. mass.

Answers

It is impossible to determine the exact position and momentum of electron simultaneously. Therefore, option B is the correct answer.

According to Heisenberg’s uncertainty principle,it is impossible to determine simultaneously, the exact position and momentum of an electron.

Mathematical expression

ΔX.ΔP ≥ h/4π

ΔX = uncertainty in position

ΔP = uncertainty in momentum

h = Plank’s constant

π= Pi

Thus, we can conclude its nearly impossible to determine electron’s exact position. Therefore, option B is the correct answer.

What is not needed for a charge to flow through a conducting wire?A. an electrical insulator

B. a wire connected in a complete loop

C. a source of electrical energy

Answers

Answer: The correct answer is an electrical insulator.

Explanation:

Insulator : It is a material which resists the flow of electrons. It has high resistance in comparison to the conductor.

Conductor: It is a material which allows the flow of electrons. It has low resistance in comparison to the conductor.

Battery is a source of electrical energy. It forces the electrons to flow. The rate of flow of electrons constitutes the current.

In the given problem, an electrical insulator is not needed for a charge to flow through a conducting wire.

To design the circuit and to make a current flow in the circuit, a battery, a wire connected in a complete loop and a source of electrical energy are needed.

Therefore, the correct option is (C).

An electrical insulator would not be needed for a charge to flow through a conducting wire.
