Answer:

v = 282.84 m / s

Explanation:

The speed of a wave in a wire is given by the equation

.v = √ T /ρ

Where v is the speed of the wave, T the tension in the wire and ρ the density of the wire

If the tension is doubled

T = 2T₀

v = √ (2T₀ / ρ)

v = √2 √ T₀ / ρ

v = √2 v₀

calculate

v = √2 200

v = 282.84 m / s

Answer with Explanation:

We are given that

Constant speed of Jane=12.6 m/s

a.When Fred can throw the ball 30 m/s

We have to find the angle relative to the horizontal when he throw the ball in order for Sue to see the ball travel vertically upward.

Let $\theta$ be the angle .

Therefore,

$30 cos\theta=12.6$

$cos\theta=\frac{12.6}{30}=0.42$

$\theta=cos^{-1}(0.42)=65.165^{\circ}$

b.We have to find the height to which ball reach.

$v^2-v^2_0=2aS$

$S=\frac{v^2-v^2_0}{2a}=\frac{0-(30 sin65.165)^2}{2(-9.81)}$

$S=37.78 m$

What is the value of x? enter your answer in the box. Mm triangle v t k with segment t y such that y is on segment v k, between

Crank

Answer: 98 millimeters

Explanation:

Since angle VTY is congruent to angle VTK, segment TY bisects angle VTK. Since Y is on segment VK, between V and K, we can use the Angle Bisector Theorem, which states that

(1)

Since x= VK = VY + YK, we need to obtain VY since YK = 68.

VY is obtained by multiplying the denominator YK on both sides of equation (1). So,

Hence,

x = VK = VY + YK

x = 30 + 68

x = 98 millimeters
