The net force on the object is zero, so it has no acceleration. It moves in a straight line and at a constant speed (which may be zero).
Answer:
F_net = B -W
The forces of action and reaction are the weight of the balloon that is the force of attraction of the Earth and the outside so the balloon pulls the earth that has an upward direction and is applied to the planet
Explanation:
A hot air balloon is subjected to the force of its weight directed towards the center of the Earth. The thrust due to the cold air released, this thrust is directed upwards.
If we assume that the balloon rises at a constant speed
F_net = B -W
F_neta = ρ g V_body - ρ_body g V_body
The forces of action and reaction are the weight of the balloon that is the force of attraction of the Earth and the outside so the balloon pulls the earth that has an upward direction and is applied to the planet
Answer:
The angle it subtend on the retina is
Explanation:
From the question we are told that
The length of the warbler is
The distance from the binoculars is
The magnification of the binoculars is
Without the 8 X binoculars the angle made with the angular size of the object is mathematically represented as
Now magnification can be represented mathematically as
Where is the angle the image of the warbler subtend on your retina when the binoculars i.e the binoculars zoom.
So
=>
Generally the conversion to degrees can be mathematically evaluated as
Ok to distinguish the difference you just find out why there's science lol.......anyways.....Mass is the amount of space being taken up in a certain place (or possibly all the world) and weight is the heaviness of an person or thing kk??? also if my answer was best, plzz give brainliest (trust me i need it) Have a great day and Christmas (if u celebrate it)!!
Aristotle believed that the Earth was orbited by the sun, moon, and the other planets which he referred to as Celestial Bodys
