Answer:
0.211 kg
Explanation:
specific heat capacity of copper = 385 J/Kgk
heat loss by copper = mcθ = 3.8 × (8 - 84 ) × 385 = - 111188 J
heat needed to raise the temperature of water from 0°C to 8°C
= mcθ = 1.2 kg × 4180 × ( 8 - 0) = 40128 J
111188 J - 40128 J = 71060
71060 = ml
71060 / 336000 = mass of ice where latent heat of fusion = 3.36 × 10⁵JKg⁻¹
m = 0.211 kg
The horizontal distance traveled by the venom before it hits the ground is 0.6 m

What is Projectile ?</h3>
A stone or ball or anything projected is known as a projectile.
Given that a spitting cobra rears up to a height of 0.420 m above the ground and launches venom at 2.50 m/s, directed 35.0° above the horizon.
Assuming air resistance is neglected, the parameters to be considered are;
The ball we reach the ground at the same time when it is dropped vertically or horizontally.
In a vertical direction,
h = 1/2g
Substitute all the parameters into the formula
0.42 = 1/2 x 9.8 x
0.42 = 4.9
= 0.42/4.9
= 0.0857
t =
t = 0.29 s
The horizontal distance traveled by the venom before it hits the ground will be
Distance = ucosФ x t
Distance = 2.5cos35 x 0.29
Distance = 0.599 m
Distance = 0.6 m
Therefore, the horizontal distance (in m) traveled by the venom before it hits the ground is 0.6 m

Answer:
The correct option is;
Light energy, which shines on the area around the fire
Explanation:
From the given figure the flame is visible, as the translucent region which shows that the heat from the fire causes flammable organic (carbon containing) vapors to rise and as the vapors get ignited to burn, the heated carbon atoms including the other atoms present in the burning vapor emit light energy due to their incandescent (emitting light when heated) nature, in the same manner an incandescent electric bulb produces light.
Light energy is the visible form of electromagnetic radiation that consists of packets of electromagnetic energy called photons which are emitted by the atoms of a heated incandescent material.
Displacement is distance in one particular direction. Distance is the route taken without worrying about the direction.
To find the displacement draw a straight line from the start point to the end point. Measure the length and use the scale to find the real distance.
