Answer:
48 degress
Explanation:
An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. In the United States, we use the Modified Mercalli Scale. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Therefore, each earthquake produces a range of intensity values, ranging from highest in the epicenter area to zero at a distance from the epicenter.
1.Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
Answer:
Primero, sabemos que la densidad de el oro es:
Densidad = 19.3 g/cm^3
Sabemos que nuestro metal tiene una masa de 0.75 kg, y un volumen de 340 cm^3.
Primero deberíamos reescribir la masa en gramos, pues la densidad está escrita en gramos.
Sabemos que:
1 kg = 1000g
Entonces:
0.75 kg es 0.75 veces 1000g, esto nos da:
0.75kg = 0.75*(1000g) = 750g
Entonces tenemos:
masa = 750g
volumen = 340cm^3
Ahora debemos recordar que:
densidad = masa/volumen
Entonces la densidad de este metal es:
densidad = 750g/340cm^3 = 2.21 g/cm^3
Si la comparamos con la densidad del oro, podemos ver que esta es mayor.
Entonces podemos concluir que este metal no es oro.
Answer:
Initial velocity = 10 m/s
θ = 60°
This is the case of projectile motion
So the horizontal component of velocity 10 m/s = 10 cosθ
u = 10 cosθ
u = 10 cos 60°
u=5 m/s
x= 5 m
So in the horizontal direction
x = u .t
5 = 5 .t
t = 1 sec The vertical component of velocity 10 m/s = 10 sinθ
Vo= 10 sinθ
Vo= 10 sin 60°
Vo = 8.66 m/s
h=3.75 m
So height of robot = 3.75 - 0.75 m
height of robot =3 m
Radiation can pass through any phase of matter.
Examples:
Light, radio, heat, and X-rays, all pass through glass (solid),
water (liquid), and air (gas) very easily.
(Moreover, I would be remiss if I failed to point out in addition that
microwave radiation passes through meatloaf and coffee with only
partial attenuation due to absorption.)
