I believe a is the answer enjoy
The distance from Point A=500 mm
Explanation:
M := 40kg c := 200mm
μs := 0.3 d := 3
a := 400mm e := 4
b := 800mm
Initial guesses: 
:= 200 N P := 50N

Answer:
Denial is a defense mechanism which allows an individual not to accept the truth about a painful experience or distress.
Explanation:
Denial is a way of coping with distress. Denial means trying to reject the truth about a situation. It could be denying the truth about your personal situation or about someone else like your friends, parents or siblings.
Denial is a defense mechanism used to protect oneself against accepting a painful experience or situation in life.
Denial could be helpful or harmful.
It can be helpful when one begin to take action about a problem by seeking for help.
It could be harmful if you don't seek for help when in distress.
A person engaged in denial is trying to stay sane and act normal like everything is alright with he/she. The person tries to block negative thought and focus on more positive thoughts.
Example of denial
1) A young lady who just experienced a breakup from her boyfriend who she truly loves but act like the breakup doesn't affect her or that she doesn't love the guy.
2) A 21 year old person who has cancer and has about 10 months to live have plans of celebrating his/her 25th birthday in a big way
3) When someone is harboring the thought that coronavirus is not real or it is not a serious disease.
Answer:
a. the base must be more positive than the emitter
Explanation:
A transistor can be defined as a semiconductor component that is used to control the flow of voltage or current and as a gate (switch) for electronic signals. Thus, a transistor allows for the amplification, control and generation of electronic signals in a circuit. The three (3) basic parts of a transistor are; base, emitter and collector.
Basically, there are two (2) main types of transistor and these are;
1. PNP transistor.
2. NPN transistor.
Biasing of a transistor can be defined as the process of providing the controlled amount of direct current (DC) voltage or current conditions so as to enable the transistor amplify the alternating current (AC) input signal correctly.
Hence, to forward bias an NPN transistor, the base must be more positive than the emitter because the majority carriers are electrons which are moved from the n-type region to the p-type region while the minority carriers are holes.
This ultimately implies that, for an NPN transistor to conduct current in milliamps, its base-emitter junction must be forward biased.
