Answer:
magnitude=2085.99 kg
direction angle= 23.18°
Explanation:
let the forces be x,y
x = 1670cos(90°+30°) i +1670sin(90°+30°) j,
y = 1250cos(-90°-60°) i +1250sin(-90°-60°) j
x = 1670cos(120°) i + 1670sin(120°) j,
y = 1250cos(-150°) i + 1250sin(-150°) j
resultant force = x+y
resultant force = 1670cos(120°) i +1670sin(120°) j + 1250cos(-150°) i +1250sin(-150°) j
taking i and j term together
resultant force = (1670cos(120°) +1250cos(-150°)) i +(1670sin(120°) +1250sin(-150°)) j
resultant force = -1917.53 i +821.26j
magnitude=2085.99 kg
direction angle=
direction angle= 23.18°
The resultant force will be
twice the applied force.In a lever, the total distance from the applied force to the fulcrum is
the effort arm. And, the distance between load and the fulcrum is
the load arm.
When the effort arm is two times the load arm, it means the resultant force will be twice the applied force.
Because, Force = displacement × speed
The answer is : B. The compass will spin exactly 360 Degrees
Compass will point out to the earth's magnetic field. If we change the direction of the current , we created an effect which make the compass detect the magnetic field in the exact opposite direction, that is why it will flip exactly 180 degrees

Kindly check explanation
Explanation:
Given the following :
Distance between Ranjan and Gomez house = 9km
Start time = 6'o clock
Time he arrived at Gomes house = 7'o clock
Time used for chatting during this period = 5 minutes
Distance covered in 40minutes = 6km
Time spend for second part of the journey = (60 - (40 + 5))minutes = 15 minutes = 15/60 = 0.25 hoir
Distance covered during second part of journey = 9 - 6 = 3 km
Speed = distance / time
Speed = 3km / 0.25 hr = 12km/hr
Average speed for entire journey :
First part :
Speed = distance / time
Time = 40 minutes = (40/60) = 0.667 hour
Speed = 6km / 0.667 hour = 9km / hr
Average speed :
(First part + second part) / 2
(9km/hr + 12km/hr) / 2 = 21km/hr / 2 = 10.5 km/hr
= 10.5km/hr
it will move the object if you apply force, because of that it will stay the same with newton's law.
