Answer:
Distance, S = 13m
Explanation:
Given the following data;
Initial velocity, u = 4m/s
Final velocity, v = 9m/s
Time, t = 2 seconds
To find the distance, S;
First of all, we would determine the acceleration of the shark.
Acceleration = (v - u)/t
Acceleration = (9 - 4)/2
Acceleration = 5/2
Acceleration = 2.5m/s²
Now, to find the distance we would use the second equation of motion
S = ut + ½at²
Substituting into the equation, we have
S = 4(2) + ½*2.5*2²
S = 8 + 1.25*4
S = 8 + 5
Distance, S = 13m
What is NOT one of the three primary resources that families have to reach financial goals? It is c) education
Answer: E = 0.85
Therefore the efficiency is: E = 0.85 or 85%
Explanation:
The efficiency (e) of a Carnot engine is defined as the ratio of the work (W) done by the engine to the input heat QH
E = W/QH.
W=QH – QC,
Where Qc is the output heat.
That is,
E=1 - Qc/QH
E =1 - Tc/TH
where Tc for a temperature of the cold reservoir and TH for a temperature of the hot reservoir.
Note: The unit of temperature must be in Kelvin.
Tc = 300K
TH = 2000K
Substituting the values of E, we have;
E = 1 - 300K/2000K
E = 1 - 0.15
E = 0.85
Therefore the efficiency is: E = 0.85 or 85%
The point of origin of an epileptic seizure is called the focus. It is the part of the brain that is affected by epilepsy. This is a term used for people with partial epilepsy. The focus can be the frontal lobe, occipital lobe, mesial temporal lobe or the parietal lobe. During seizures, it is the that specific part of the brain that is being effected. Seizures happen when a surge in the electrical activities happen on certain parts. Symptoms are contractions of the muscles, blackouts and visual disturbances. Seizures can be cured and, for partial epilepsy, they are treated with AEDs or antiepileptic drugs.
Answer:
B. Technician B
Explanation:
The statement made by Technician A is not right because for an RWD vehicles, its front bearing assembly is not used for sustaining the bearing adjustment. The statement made by the Technician B is right because the main reason for staking the bearing assembly of the wheel of a FWD vehicle is to ensure that the torque is at a specific value. Thus, only Technician B is correct.
