Answer:
<em>The work done by the car is 363 kJ</em>
Explanation:
Work : Work is said to be done when a Force moves an object through a certain distance. Work and Energy are interchangeable because they have the same unit. The unit of work is Joules (J).
Mathematically work done can be expressed as,
E = W = 1/2mv²
W = 1/2mv²................................ Equation 1
Where E = Energy, W = work done, m = mass of the car, v = velocity of the car
<em>Given: m=1500 kg, v=22 m/s</em>
<em>Substituting these values into equation 1</em>
<em>W = 1/2(1500)(22)²</em>
<em>W = 750 × 484</em>
<em>W = 363000 J</em>
<em>W = 363 kJ</em>
<em>Thus the work done by the car is 363 kJ</em>
Answer:It's important to listen to your body and what it's really saying. Don't listen, and your exercise could wind up working against you, actually triggering muscle loss and fat gain. Plus, pushing too hard comes with a huge risk of injury-and all of your training won't do you much good if you're sidelined on race day.
Explanation:
As there is no postive or negative assigned so
Initial velocity= -2.8759
Displacement= 0.5at^2+ut
= 0.5(-1.77)(3.33)^2+(-2.8759)(3.33)=-19.4m
Answer:
Electronegativity is a chemical property at the top of the periodic table
Explanation:
electronegativity is a chemical property that measures the ability of an atom to attract a bonding pair of electrons when it is part of a compound
it's a property of atom that increases as you go to the right and up.
One example is the Pauling scale. it is a numerical scale of electronegativities. It was first developed by Linus Pauling.
it is commonly used to calculate the ability of electronegativity to attract electrons to itself.
The most common electronegative element is Flourine, having an assigned value of 4.0, ranging down to caesium and francium, having the least electronegative at 0.7
Answer: chemical → kinetic → electrical → light
Explanation: At the same time when the generator lights up the bicycle lamp the lamp lights up using electrical energy so mechanical energy is also transformed into electrical energy.
