**Physics kinetic energy**

because v is the only thing changing the value of m is not relevant. to find out what would happen to the energy we compare the differences in v ie 10^2 = 100 5^2 = 25 since the new v value is a quarter of the previous value the answer is (d) alternatively, your reasoning ...

An initial-value problem is given by the differential equation, f(x,y) = x + y, y(0) = 1.64 The Euler-midpoint method is used to find an approximate value to y(0.1) with a step size of h = 0.1. Then use the integrating factor method, to find the exact value of y(0.1). Hence, ...

The phase constant φ is the value of |ωt| at the point where x has its maximum value, for ω*t between -2 pi and 0. The value of (ωt + φ) will be zero there; the cos function will have its maximum value.

Not only that, but you are wrong on number 6. A minimum value of f'(x) at x = c does NOT imply an extreme value, although the reverse is certainly true if the sign changes from - to +. f''(x) could be undefined at f'(c) which would make it a critical value of f'(x) since it is...
