Find the sine,cosine and tangent ratios​

Physics
1 answer:
kotykmax [81]4 years ago
8 0

Answer:

1)  

sinA=5/13       sinB=12/13

cosA= 12/13   cosB=5/13

tgA=5/12      tgB=12/5

2)

sinA=8/17       sinB=15/17

cosA= 15/17   cosB=8/17

tgA=8/15      tgB=15/8

3)

sinA=7/25       sinB=24/25

cosA= 24/25   cosB=7/25

tgA=7/24      tgB=24/7

4)

sinA=1/2       sinB=√3 /2

cosA= √3 /2   cosB=1/2

tgA=1/√3       tgB=√3  

5)

sinA=1/√2       sinB=1/√2

cosA= 1/√2   cosB=1/√2

tgA=1       tgB=1

Y_Kistochka [10]

Answer:

529.15 m/s

Explanation:

h = Maximum height = 70000 m

g = Acceleration due to gravity = 2 m/s²

m = Mass of sulfur

As the potential and kinetic energies are conserved

mgh=\dfrac{1}{2}mv^2\\\Rightarrow h=\dfrac{v^2}{2g}\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 2\times 70000}\\\Rightarrow v=529.15\ m/s

The speed with which the liquid sulfur left the volcano is 529.15 m/s

Consider a traveling wave described by the formula
Harrizon [31]

Answer:

The wave is traveling in the +x direction.

Explanation:

The equation of a wave is given by the formula as :

y(x,t)=A\ sin(kx-\omega t)

Here,

A is the amplitude of wave

(kx-\omega t) is the phase of wave

\omega is the angular frequency of the wave

We need to find the correct statement out of given options. The given equation can be rewritten as :

y(x,t)=A\ sin(\omega t-kx)

Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).

Which property of X-rays allows them to enter our bodies and create pictures of our bones and other internal structures?
Degger [83]

Answer:

(A) Their high energy

Explanation:

The higher the energy of the x-ray the more "likely" they will pass through.

The x-ray is electromagnetic energy caused by energy changes in an electron.

X-ray are energetic and have enough energy to break up molecules. That is what reveals the bad or damaged cells in our body.

C. Series

Consider resistors in a circuit - if all the resistors in the circuit are in series and one of the resistors fails then no current can flow thru the circuit,

If the resistors are in parallel then then each resistor experiences the same voltage drop regardless of whether or not any resistor in particular is carrying current.
