Answer:
D. The cart is moving at a constant speed or velocity
Explanation:
Equilibrium is a state of body in which it is either at rest or moves with uniform velocity. The sum of forces acting on such a body is always zero and the sum of all the torques acting on it is also zero.
There are two types of equilibrium as follows:
Static Equilibrium: When a body is at rest it is said to be in static equilibrium.
Dynamic Equilibrium: When a body is moving with constant velocity, then it is said to be in dynamic equilibrium.
Hence, the correct option here will be:
<u>D. The cart is moving at a constant speed or velocity</u>
Force applied by the lever to the object=2700 N
Explanation:
Mechanical advantage= 
mechanical advantage= 5.4
effort force= 500 N
we need the load force
5.4= load/500
load=2700 N
Thus the force applied by the lever to the object=2700 N
Answer:
The acceleration and time are 588 m/s² and 0.071 sec respectively.
Explanation:
Given that,
Speed = 42.0 m/s
Distance = 1.50 m
(a). We need to calculate the acceleration
Using equation of motion


Put the value in the equation


(b). We need to calculate the time
Using equation of motion




Hence, The acceleration and time are 588 m/s² and 0.071 sec respectively.
A Safety Data Sheet (SDS) provides even more information on chemicals than a label: True.
<h3>What is a
Safety Data Sheet (
SDS)?</h3>
A Safety Data Sheet (SDS) can be defined as a text-based document (bulletin) that is developed to provide more information with respect to the chemical and physical properties of a chemical compound, substance or equipment such as:
Additionally, a Safety Data Sheet (SDS) contains information on the potential health hazards and safety precautions for proper use, handling, storage and transportation of a chemical compound, substance or equipment.
In conclusion, we can deduce that a Safety Data Sheet (SDS) provides even more information on chemicals than a label, which only contains lesser information about a product.
