Put a parashoot on it so it touches the ground lightly and carefully
Answer: False
Explanation:
because according to universal law of gravitation, every object attracts every other object in the universe.
according to the newton's third law, for every action there is equal and opposite reaction.
So, both the saturn and pan exerts same force on each other
But from the newton's second law we have, F = ma & a = F/m
so, from the above equation acceleration produced by pan is high compared to the acceleration produced by saturn.
Therefore, acceleration produced by saturn is lower than the acceleration produced by pan
but force exerted by saturn is equal to the force exerted by pan
So, the answer is false

Answer:
30 cm
Explanation:
To solve this problem, we use the lens equation:
where
f is the focal length of the lens
p is the distance of the object from the lens
q is the distance of the image from the lens
In this problem, we know that
q = -30 cm is the distance of the image from the lens; it is negative because the image is formed in front of the lens, so it is a virtual image
We also know that the size of the image is twice that of the object, so the magnification is 2:
where M is the magnification of the lens. Solving this equation for p,
So, the distance of the object from the lens is 15 cm.
Now we can finally solve the lens equation to find f, the focal length:
Hmm...
dam power plant (not sure if this is considered renewable): benefits: as it creates a tourist spot bringing more money and provides electricity.
disadvantages: restricts flow of water to farms, costs millions to build.
solar power plant: benefits: sunlight just keeps coming, produces a lot of electricity for maybe half the cost.
disadvantages: takes a large crew to maintain, mostly needs to be in an open area.
Wind farm: benefits: wind we don't have to worry about much, just blows through and turns the turbines, and can produce electricity almost 24/7.
disadvantages: unsightly, needs open space and costs a lot to build
Take your pick!
Answer:
77000 J
Explanation:
Formula for the heat energy is;
Q = m•c•Δt
We are given;
mass; m = 2 kg
Change in temperature; Δt = 110 - 10 = 100 °C
From online values, specific heat capacity of copper is; c = 385 J/kg.°C
Thus;
Q = 2 × 100 × 385
Q = 77000 J
