Answer:
for X, it's 50 times cos 35.
for y, it's 50 times sin 35.
A pressure system is a relative peak or lull in the sea level pressure distribution. The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg). High- and low-pressure systems evolve due to interactions of temperature differentials in the atmosphere, temperature differences between the atmosphere and water within oceans and lakes, the influence of upper-level disturbances jargon as well as the amount of solar heating or radiational cooling an area receives. Pressure systems cause weather experienced locally. Low-pressure systems are associated with clouds and precipitation that minimize temperature changes through the day, whereas high-pressure systems normally associated with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day. Pressure systems are analyzed by those in the field of meteorology within surface weather maps.
Harper used the the frequency principle (F) by planning to work out 4-5 days a week. Frequency is how often you exercise, usually on a weekly basis.
She used the intensity principle (I) by deciding to exercise on a moderate level, rather than, for example, an intense workout. Intensity is basically how hard you exercise and push yourself.
She then used the time (T) principle by choosing to workout for 60 mins per day. Time meaning how much time you spend working out each day.
And lastly, she used the type (T) principle by devising a specific type and/or set of exercise(s) to do, which in her case, is drills, jogging, and weight lifting.
So all in all, Harpers frequency is 4-5 days per week, her intensity is moderate, her time is 60 mins/day, and type is basketball drills, jogging and weight lifting.
Hope I helped! :)
The work done is 8427 J while the energy expended is 80.25 W.
<h3>What is work done?</h3>
Work done is defined as the product of the force and the distance. We know that the work done in a gravitational field is given as;
W = mgh
Total mass of the water bucket and chain = 13.9 kg + 19.3 kg = 33.2Kg
Distance covered = 25.9 m
W = 33.2Kg * 9.8 m/s^2 * 25.9 m
W = 8427 J
Recall that the work done = Energy expended
Power = Energy expended/ Time
Power = 8427 J/ 1.75 * 60 seconds
Power = 80.25 W
