Answer:
3360 N
Explanation:
In a first-class lever, the effort force and load force are on opposite sides of the fulcrum.
The lever is 5 m long. The load force is 1.50 m from the fulcrum, so the effort force must be 3.50 m from the fulcrum.
The torques are equal:
Fr = Fr
(1440 N) (3.5 m) = F (1.5 m)
F = 3360 N
<span>Work equals
force times distance. When you move an object, you are exerting a force onto
it. By exerting a force on the object, you are actually displacing it from its
initial position. You cannot apply force to the object without altering its
position. Keep in mind that when you exert work, you are exerting energy too. So
the work must have a unit in joules in SI units. Force is in newtons or
kilogram meter per second squared. And distance is in meters. So you will have
newton-meter or joules. </span>
Answer:
4.12 m/s^2
Explanation:
unbalanced force means the presence of resultant force (net force)
f = 28N
m = 6.8kg
a = ?
? = 28/6.8
= 4.1176...
approximately = 4.12 m/s^2

Answer:
It's terrifying, but a relief that you know your children isn't home alone.
Explanation:
Why, it's because sometimes you don't know what is going on in the daycare. The baby/ the child you gave birth to is in the hands of a random stranger. It's also a relief knowing that at least someone is taking care of your child, or hope to be. Instead of your child, no adult supervision or any people watching your child can result in death, injuries, and more since your child is alone.
