Answer:
El alcance de la bala es 3464,1 m.
Explanation:
El alcance de la bala se puede calcular como sigue:
En donde:
y: es la altura final = 0
: es la altura inicial = 0
x: es el alcance
θ: es el angulo respecto a la horizontal = 30°
: es la velocidad inicial = 200 m/s
g: es la gravedad = 10 m/s²
Entonces, tenemos:
Por lo tanto, el alcance de la bala es 3464,1 m.

Answer:
98.13m
Explanation:
Complete question
Daniel is 50.0 meters away from a building. Tip of the building makes an angle of 63.0° with the horizontal. What is the height of the building
CHECK THE ATTACHMENT
From the figure, using trigonometry
Tan(θ ) = opposite/adjacent
Where Angle (θ )= 63°
Opposite= X = height of the building
Adjacent= 50 m
Then substitute the values we have
Tan(63)= X/50
1.9626= X/50
X= 1.9626 × 50
X= 98.13m
Hence, the height of the building is 98.13m
Answer:
Both student are correct.
Explanation:
Given :
Student 1: Nuclear fusion powers the Sun, so activity like sunspots and flares must be caused by a change in the fusion rate or the type of fusion.
Student 2: Fusion is constant, keeping the Sun a nice temperature; changes on the surface are caused by the Sun's magnetic field
There are two types of nuclear reaction,
Fusion:
Two lighter atom combine together are produce new atom.
In case of fusion large amount of energy produces and fusion powers the sun. In case of sun two hydrogen atom combine together and helium produces so statement 1 is true.
Sun posses large magnetic field due to magnetic field sun spot created like magnet there are two poles N and S, magnetic field lines goes from N to S.
Sun spot are produces because of change in magnetic field and change in temperature. So statement 2 is also true.
Answer:
D
Explanation:
calculate effective resistance of the resistors
= 80 + 120
= 200
overall resistance = 48 ohms
so overall current flowing through circuit
I = V / R
I = 12 / 200
I = 0.06 A
since circuit is in series, current is same at every point so...
potential difference across 80 = R x I
= 80 x 0.06
answer is potential difference = 4.8 V
hope this helps
