Ganezh [65]
Let the mass of planet and moon be Mp and Mn respectively.
And the distance between them is "r"

Then according to Newton's law of gravitation,

The force with which the planet and the moon attract esch other is
1) directly proportional to the product of their masses i.e. Mp * Mn

2) inversly proportional to the square of the distance between them i.e r ^2

Therefore,F =. G (Mp* Mn)/r^2
Where,G is gravitational constant

To protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. In one such ep
I am Lyosha [343]

Answer:

Part a)

\theta = 48 degree

Part b)

v = 13.45 m/s

Explanation:

Part a)

mass of the Falcon bird is given as

m = 600 g

initial speed of the bird is

v_i = 20 m/s

final speed of the bird is given as

v_f = 5 m/s (opposite direction)

So here the impulse given by falcon bird is given as

I = m(v_f - v_i)

I = 0.600(20 + 5)

I = 15 kg m/s

now the final momentum of Raven bird in perpendicular direction is given as

I = mv_y

15 = 1.50 v_y

v_y = 10 m/s

now the change in the angle of the raven bird is given as

tan\theta = \frac{v_y}{v_x}

tan\theta = \frac{10}{9}

\theta = 48 degree

Part b)

Final speed of the raven bird is given as

v^2 = v_x^2 + v_y^2

v^2 = 9^2 + 10^2

v = 13.45 m/s

Suppose 1 kg of Hydrogen is converted into Helium. a) What is the mass of the He produced? b) How much energy is released in thi
morpeh [17]

Answer:

a) m = 993 g

b) E = 6.50 × 10¹⁴ J

Explanation:

atomic mass of hydrogen = 1.00794

4 hydrogen atom will make a helium atom = 4 × 1.00794 = 4.03176

we know atomic mass of helium = 4.002602

difference in the atomic mass of helium = 4.03176-4.002602 = 0.029158

fraction of mass lost = \dfrac{0.029158}{4.03176}= 0.00723

loss of mass for 1000 g = 1000 × 0.00723 = 7.23

a) mass of helium produced = 1000-7.23 = 993 g (approx.)

b) energy released in the process

E = m c²

E = 0.00723 × (3× 10⁸)²

E = 6.50 × 10¹⁴ J
