im probably wrong but probably increase because if they get closer the static/sparks to cause a reaction
The volume of the balloon is given by:
V = 4πr³/3
V = volume, r = radius
Differentiate both sides with respect to time t:
dV/dt = 4πr²(dr/dt)
Isolate dr/dt:
dr/dt = (dV/dt)/(4πr²)
Given values:
dV/dt = 72ft³/min
r = 3ft
Plug in and solve for dr/dt:
dr/dt = 72/(4π(3)²)
dr/dt = 0.64ft/min
The radius is increasing at a rate of 0.64ft/min
The surface area of the balloon is given by:
A = 4πr²
A = surface area, r = radius
Differentiate both sides with respect to time t:
dA/dt = 8πr(dr/dt)
Given values:
r = 3ft
dr/dt = 0.64ft/min
Plug in and solve for dA/dt:
dA/dt = 8π(3)(0.64)
dA/dt = 48.25ft²/min
The surface area is changing at a rate of 48.25ft²/min
Answer:
A. Parallel to the ground, approximately toward the golfer's shoulders
Explanation:
Elliptical path represent the motion of the golf club.
From the figure we have the motion of the club. So the acceleration provided will be centripetal acceleration so halfway through the swing the direction of acceleration will be towards the golfer's shoulder.
Answer:
-main-sequence star
-protostar with jets
-contracting cloud trapping infrared light
-molecular-cloud fragment
Explanation:
The Life of a Star of about one Solar Mass. Small stars have a mass upto 1 1/2 times that of the Sun. Stars are planetary bodies that revolve in space. They are the combination of hydrogen and helium gases
seven main stages of a star formation are
A Giant Gas Cloud. A star begins life as a large cloud of gas. ...
A Protostar Is a Baby Star. ...
The T-Tauri Phase. ...
Main Sequence Stars. ...
Expansion into Red Giant. ...
Fusion of Heavier Elements. ...
Supernovae and Planetary Nebulae.
But ranking them according to the central temperature, from highest to lowest. will be
-main-sequence star
-protostar with jets
-contracting cloud trapping infrared light
-molecular-cloud fragment
