The future perfect tense forms are made by putting ‘will / shall + have’ before the past participle from the verb. these sentences can be changed into the passive if the active verb has an object
i hope this helps :D thanks
<u>Answer:</u>
The plasma membrane encloses specific structures.
<u>Explanation:
</u>
plasma membrane is also called as cell membrane. Plasma membrane only allows the particle to get in and pass out of the cell by osmosis and diffusion method from the outside environment. It is responsible for the molecular traffic inside the cell.
It helps in maintaining the shape of the cell. It has many proteins in it. Therefore cell membrane are responsible for having specific structures.
Answer:
a) 2.18 m/s^2
b) 9.83 m/s
Explanation:
The flywheel has a moment of inertia
J = m * k^2
Where
J: moment of inertia
k: radius of gyration
In this case:
J = 144 * 0.45^2 = 29.2 kg*m^2
The block is attached through a wire that is wrapped around the wheel. The weight of the block causes a torque.
T = p * r
r is the radius of the wheel.
T = m1 * g * r
T = 18 * 9.81 * 0.6 = 106 N*m
The torque will cause an acceleration on the flywheel:
T = J * γ
γ = T/J
γ = 106/29.2 = 3.63 rad/s^2
SInce the block is attached to the wheel the acceleration of the block is the same as the tangential acceleration at the eddge of the wheel:
at = γ * r
at = 3.63 * 0.6 = 2.81 m/s^2
Now that we know the acceleration of the block we can forget about the flywheel.
The equation for uniformly accelerated movement is:
X(t) = X0 + V0*t + 1/2*a*t^2
We can set a frame of reference that has X0 = 0, V0 = 0 and the X axis points in the direction the block will move. Then:
X(t) = 1/2*a*t^2
Rearranging
t^2 = 2*X(t)/a
It will reach the 1.8 m in 3.6 s.
Now we use the equation for speed under constant acceleration:
V(t) = V0 + a*t
V(3.6) = 2.81 * 3.6 = 9.83 m/s
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.
