Answer:
Velocity of rocket will be equal to 7.81 m/sec
Explanation:
We have given mass of the rocket 
Mass of fuel is given 
( As 1 kg is equal to 1000 gram )
Velocity of fuel 
= 625 m/sec
We have to find the velocity of rocket 
From conservation of momentum we know that initial momentum is equal to final momentum '
So 
, here 
is mass of rocket is velocity of rocket 
is mass of fuel and is velocity of fuel
So 
So velocity of rocket will be equal to 7.81 m/sec
Answer:
= 0.086J
Explanation:
we are given three equal charges q₁ q₂ q₃ = 1.60 μC
sides of triangle = 0.800m
U = 1/4πε₀(3q²/r)
1/4πε₀ = 9.0 × 10⁹ N.m²/C²
U = 9.0 × 10⁹ ((3 * 1.60 × 10⁻⁶)² / (0.800))
= 0.086J

yes is is true cuz when you hold the thermometer by a bulb the heat coming from the bulb will increase the thermometer
Answer:
2.26 s
Explanation:
The following data were obtained from the question:
Height (h) = 25 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =..?
The time taken for the egg to hit the floor can be obtained as illustrated below:
h = ½gt²
25 = ½ × 9.8 × t²
25 = 4.9 × t²
Divide both side by 4.9
t² = 25 / 4.9
Take the square root of both side
t = √(25 / 4.9)
t = 2.26 s
Thus, it will take 2.26 s for the egg to hit the floor.
