Given:
Amount of heat produced = 100 kcal per hour
Let's find the rate of energy production in joules.
We know that:
1 calorie = 4.184 Joules
1 kcal = 4.184 Joules
To find the rate of energy production in Joules, we have:
Therefore, the rate of energy production in joules is 418.4 kJ/h which is equivalent to 418400 Joules
ANSWER:
418.4 kJ/h
The horizontal component is 2.0 cos(30°) = 1.732 m/s²
The vertical component is 2.0 sin(30°) = 1 m/s²
Gravitational potential energy can be given by the equation
PE = mgh
where m is the mass,
g is the gravitational constant 9.81 or 10 depending on rounding
and h is the height
well weight is a force equiavlent to
W= m*g
so comparing that to the potential energy equation, divide the potential energy by the height and you will get weight in Newtons
Answer:
S = 11488.42 m
Explanation:
Given,
The speed of the jet, v = 0.74 Mach
= 253.82 m/s
The altitude of the jet, h = 10000 m
Since the jet is travelling horizontally, the vertical component of velocity Vy = 0
The equation for a projectile projected from a height h is given by,
S = Vx [Vy + √(Vy² +2gh)] / g
Since Vy = 0
S = Vx √(Vy² +2gh) / g
= 253.82 x √(2 x 9.8 x 10000) / 9.8
= 11488.42 m
Hence, the humanitarian aid package should be delivered ahead of distance, S = 11488.42 m
