Ship A is located 4.1 km north and 2.3 km east of ship B. Ship A has a velocity of 22 km/h toward the south and Ship B has a vel

castortr0y [4]

Answer:

a) x component = -31.25 km/hr

b) y component = 46.64 km/hr

Explanation:

Given data:

A position is 4km north and 2.5 km east to B

Ship A velocity = 22 km/hr

ship B velocity = 40 km/hr

A velocity wrt to velocity of B

$\vec{V_{AB}} =\vec{V_A} - \vec{V_B}$

$\vec{V_A} = 22 km/hr$

$\vec{V_B} = 40 cos38\hat{i} + 40sin 38 \hat{j}$

$= 31.52\hat{i} + 24.62 \hat{j}$

putting respective value to get velocity of A with respect to B

$\vec{V_{AB}} = -22 \hat {j} - (31.52\hat{i} + 24.62 \hat{j})$

$\vec{V_{AB}} = -31.52\hat{i} - 46.62\hat{j}$

a) x component = -31.25 km/hr

b) y component = 46.64 km/hr

A wave is traveling in a string at 58 m/s. when the tension is then increased 17%, what will be the resulting wave speed?

Zepler [3.9K]

the resulting wave speed=62.7 m/s

Explanation:

The speed of a wave is given by

v= $\sqrt{\frac{T}{\mu} }$

T= tension, v= velocity= 58 m/s

when the tension is increased by 17%, new tension= 1.17 T

$V'=\sqrt{\frac{1.17T}{\mu}}$

$V'=1.082 \sqrt{\frac{T}{\mu}}$

V'=1.082 V

V'=1.082 (58)

V'=62.7 m/s

An infected tooth forms an abscess (area of infected tissue) that fills with gas. The abscess puts pressure on the nerve of the

Marianna [84]

Answer:

No, the treatment won't work

Explanation:

Since the abscess is filled with gas, and is already putting pressure on the tooth nerve, applying moist heat will only aggravate the problem. The pressure of a given gas increases with temperature and so, the gas within the abscess will only put more pressure on the nerve due to the expansion of the gas within the abcess, causing her more discomfort.
