Answer:
Correct Answer: Option B
Explanation
V.R = 1sinθ=1sin30=21sinθ=1sin30=2
M.A = E×V.R100=50×2100=1E×V.R100=50×2100=1
Effort = loadM.A=1201=120N
Answer:
Hi there! Static maps are standalone images in PNG format that can be displayed on web and mobile devices without the aid of a mapping library or API. They look like an embedded map without interactivity or controls.
The Dynamic map is an interactive map where the user can freely pan and zoom. On this map, it is possible to place large amounts of markers and to link them with loaded data. This type of visualization will be stored on a server of MapCreator; the so-called hosted solution.
A topographic map is a detailed and accurate two-dimensional representation of natural and human-made features on the Earth's surface. These maps are used for a number of applications, from camping, hunting, fishing, and hiking to urban planning, resource management, and surveying.
Any moving object in space will travel in a straight line at the same speed forever, planets included. The planets would be moving in straight lines, but the sun's gravity pulls them toward it. The force of gravity causes the moving planets to travel in roughly circular orbits around the sun.
Answer:
v = 2.89 m / s
Explanation:
This is a kinematics exercise, the centripetal acceleration is
a = v² / r
where a is the acceleration, v is the velocity and r the radius
let's clear
v = √a r
let's calculate
v = √ (27 0.31)
v = 2.89 m / s
this is the speed of the drum which is constant
