A diver of mass 60 Kg dives from a height of 10 m into a swimming pool. Through the air there is resistance of 50 N a) Find the speed at which the diver enter the water b) Once in the water, the water provides an upward force of 2000 N. Find the greatest depth in water the diver reaches.
If the x̄ =87 and the s=7, the z−score that corresponds to a score X=102 is
Given the score X=72, σ=4 and z=1.64, the value of μ is
A positive point charge q1 at the origin and a negative charge q2 at x=2m. The resultant electric field is 10.8 i N/C at x=1m and -8 i N/C at x=3m. Find q1 and q2.
Suppose an average of 5 cars arrive at the parking lot every 15 minutes. What is the probability that exactly 4 cars will arrive in the next 15 minutes?
A crate at rest with a mass of 75 kg is being pushed by a force of 620 N. If the coefficient of kinetic friction between the crate and the floor is 0.55, determine how fast the crate will accelerate, and how far the crate will travel in 3.0 seconds.
how gdp is determine in a 4 sector economy explain using aggregate expenditure and aggregate output approach
An electron penetrates the region between two uniformly charged horizontal plates, but oppositely signed. Its initial speed, at half distance between the plates is 2×10 ^6 i m/s. The plates have a length of 4 cm and are 1.6 cm apart. In the whole region between the plates, the electric field ́ is uniform and perpendicular to the plates. (a) what is the maximum modulus that the vertical electric field can have so that the electron does not touch any plate?
The answer is 228 N/C but I'm not too sure how they got that?

Christine and Paul are deciding how to split their time
between writing music and lyrics for their new album. Their
PPFs for 72 h of work are shown. Christine and Paul have to
write music for 8 songs and lyrics for 12 songs (4 songs
already have music). When they are done, they can go to a
private island and relax from all their hard work. It is possible
that they will use more than 72 h.
Once they start writing lyrics and music, assuming their hired
help packs for them and their plane is waiting outside their
door, in how many hours can they board the plane to their
relaxing island getaway?
