Answer:
1004.277N
Explanation:
Given that g = 9.817 ms^-2
If the angle between the cable and horizontal is 47°.
The angle between the cable and vertical is 90-47= 43°.
The weight of the beam is mg
The weight of the beam is
= 150*9.817
The weight of the beam is
= 1472.55N
magnitude of the vertical component of the force is mgsin(tita)
= 1472.55*sin43
= 1004.277N
We know average speed =total distance/time taken
So avg speed=(85+63)/(5+5)=14.8km/hr
Answer:
False

Using your opposite hand will strengthen neural connections in your brain, and even grow new ones. It’s similar to how physical exercise improves your body’s functioning and grows muscles
Answer:
<h2> 4kg</h2>
Explanation:
Step one:
given
length of rod=2m
mass of object 1 m1=1kg
let the unknown mass be x
center of mass<em> c.m</em>= 1.6m
hence 1kg is 1.6m from the <em>c.m</em>
and x is 0.4m from the <em>c.m</em>
Taking moment about the <em>c.m</em>
<em>clockwise moment equals anticlockwise moments</em>
1*1.6=x*0.4
1.6=0.4x
divide both sides by 0.4 we have
x=1.6/0.4
x=4kg
The mass of the other object is 4kg
There are many [asteroids] between Mars and Jupiter. The orbital gap between the two planets is referred to as the Asteroid Belt.
