Answer;
Proof Surrogate.
Explanation;
A claim masquerading as proof or evidence, when no such proof or evidence is actually being offered.
Proof Surrogate is an expression used to suggest that there is evidence for a claim without actually citing any evidence. For example;
-“Scientists have known that aliens exist for years now.”
-“Everyone knows that bottled water is better for you than tap water.”
Answer:
Explanation:
The equation of force is
F = 4 sin 4 t
Compare with the standard equation
f = A sin wt
where, w is the angular frequency and A is the amplitude.
Now
w = 4 rad/s
Let the time period is T.
the relation for the time period is
the time period is defined as the time taken by the body to complete one oscillation.
So, the velocity is zero at the extreme points where the object is at time, T/4 and its odd T/2, 3T/4, 3T/2, etc.
So, the velocity is zero at time
To determine the position of the mass and the times when the velocity is zero in a mass-spring system.
To determine the position of the mass at any time, we need to solve the equation of motion for the mass-spring system. The equation is:
mx'' + kx = Fext
where m is the mass, x is the displacement of the mass from its equilibrium position, k is the spring constant, and Fext is the external force. We can solve this differential equation to find the position of the mass as a function of time.
To determine the first four times at which the velocity of the mass is zero, we need to solve for the velocity of the mass, which is given by:
v = x'
We can find the times at which the velocity is zero by finding the values of t for which x' = 0.

Horsepower= 746 W
The above is the info you will need. This is what I have done so far, but it can NOT be right:
98.3*10^15Btu/year(1 year/365 days) = 0.269315*10^15 Btu/day (0.269315*10^15Btu/day)/291 million = (0.2693*10^15 Btu/day)/291*10^6 ~0.00092548109*10^5 Btu/day = 925,481.09Btu/day
925,481.09Btu/day*(1day/24hour) = 38561.71 Btu/hour ~ 38561.7Btu/hour
1horsepower = 746 W
1 W = 3.412Btu/hr38561.7Btu/hr*(1 W/3.412 Btu/hr) ~ 11301.3 W*(1 hp/746 W) = 15.149 hp
