An elevator is being lifted up an elevator shaft at a constant speed by a steel cable. all frictional effects are negligible. in this situation, forces on the elevator are such that:_____.
A steel cable is moving an elevator up an elevator shaft at a consistent speed. The consequences of friction are all insignificant. In this case, the forces acting on the elevator are such that the cable's upward force is equal to the force of gravity pulling downward.
Second Law of Motion of Newton:Often referred to as Newton's Second Law of Motion, the Law of Force and Acceleration asserts that an object accelerates when it is subjected to a force using the formula net force = mass x acceleration (F = ma). Thus, the acceleration of the item is directly proportional to its force and inversely proportional to its mass. A body's momentum is determined by its mass and velocity together. Momentum is a vector quantity, just like velocity, having both a magnitude and a direction. The amount, direction, or both of the momentum can vary when a force is applied to a body.Learn more about the Newton 2nd law with the help of the given link:

What is tension Force?In physics, tension is defined as the pulling force transmitted axially by a string, cable, chain, or other similar object, or by either end of a rod, truss member, or other comparable three-dimensional object.
Tension can also be thought of as the action-reaction pair of forces acting at each end of the aforementioned elements. The polar opposite of compression might be tension.
CalculationOnly two forces act on the traffic light: the tension T of the cable (upward) and the weight of the traffic light (downward).
The weight is mg = 25 x 9.81 = 245.25 N
If the traffic light is at equilibrium, the resultant of the two forces must be equal to zero (Newton's second law):

BCC unit in a cell : It consists of 8 atoms on vertices and 1 atom at the centre.
Therefore, side length = 0.282 nm
1. No of atoms in the BCC cell = 1 / 8 *8 + 1 = 2 atoms
Atomic atoms = No of atoms * weight

How long will it take a car to go from a complete stop to 44 km/hr if they are accelerating
at 5m/s²?
Answer:
Time taken = 2.444sec
Explanation:
Greetings !
Given values :-
Final velocity (Vf) =44km/hr =12.22m/s Initial velocity (Vi) = 0m/sAcceleration (a)= 5m/s²Required values:-
Time taken (t) =?Solution/ work-out:-
Firstly change the km/hr value to m/s
Then, recall the Velocity-Time Equation:
[tex]vf = vi \: + at[/tex]
substitute known variables into the equation
[tex](12.22) = (0) + (5)t[/tex]
Solve for time
[tex]t = 2.444sec[/tex]
Hope it helps!!
In the worst case, a linear search locates a value in an array of length n in ____ steps.
In the worst case, a linear search locates a value in an array of length n in O(N) steps.
Briefing :The best case scenario for a linear search on a list of n items is when the goal value is equal to the very first item on the list. In these circumstances, just one comparison is required. The best case performance is therefore O(1). A linear search in linear time can perform a maximum of n comparisons, where n is the length of the list. As a result, O represents the computing complexity of linear search (N). When the search item occurs at the top of the list and is O(1), the Linear Search algorithm performs at its best. The worst-case scenario is when the search result does not appear at all or appears at the bottom of the list. The worst case scenario is O(N) because this would require N comparisons.Learn more about the Linear search algorithm with the help of the given link:

How would you connect multiple batteries in order to get the biggest possible voltage?
We connect multiple batteries in series in order to get the biggest possible voltage.
Series connection
A circuit is set to be connected in series when there is same flow current through all the component in the circuit.
There is only one path for current to flow.
Parallel connection
A circuit is said to be connected in parallel when all the components are connected across each other's lead.
If we connect two batteries in series then the two batteries add up their voltage. And we have the combined voltage. (as shown in image)
series means connecting one anode to the another cathode of next.
similarly if batteries placed in parallel then the voltage in circuit is same as of individual battery.
We connect multiple batteries in series in order to get the biggest possible voltage.
