Answer:
It would be static discharge and conduction
Explanation:
The conduction of static energy is pulled throughout the clothes and left over static electricity is what causes the spark.
Answer:
5501 kg/m^3
Explanation:
The value of g at the Earth's surface is
where G is the gravitational constant
M is the Earth's mass
is the Earth's radius
Solving the formula for M, we find the value of the Earth's mass:
The Earth's volume is (approximating the Earth to a perfect sphere)
So, the average density of the Earth is
0.119cm/s is the radius of the balloon increasing when the diameter is 20 cm.
<h3>How big is a circle's radius?</h3>
The radius of a circle is the distance a circle's center from any point along its circumference. Usually, "R" or "r" is used to indicate it.
A circle's diameter cuts through the center and extends from edge to edge, in contrast to a circle's radius, which extends from center to edge. Essentially, a circle is divided in half by its diameter.
dv/dt = 150cm³/s
d = 2r = 20cm
r = 10cm
find dr/dt
Given that the volume of a sphere is calculated using
v = 4/3πr³
Consider both sides of a derivative
d/dt(v) = d/dt( 4/3πr³)
dv/dt = 4/3π(3r²)dr/dt = 4πr²dr/dt
Hence,
dr/dt = 1/4πr².dv/dt
dr/dt = 1/4π×(10)²×150
dr/dt = 1/4π×100×150
dr/dt = 0.119cm/s.

Explanation:
It is given that,
Initial speed of a golfer, u = 29 m/s
If it travels the maximum possible distance before landing. It means that it is projected at an angle of 45 degrees.
(a) We need to find the time spent by the ball in the air. It can be calculated by using second equation of motion.
Here,
a = -g
s = 0 (it is displacement and it is equal to 0 as the ball lands on the green).
So,
So, it will take 4.184 seconds in the air.
(b) let x is the longest hole in one that the golfer can make if the ball does not roll when it hits the green. It can be given by :
Hence, this is the required solution.
-Try one new workout every month. Keeping the same exact routine when it comes to your fitness is never a good thing.
-More water
With any diet, the most important thing to remember is to stay hydrated. Drinking water will support your body with digestion, transporting nutrients to your bones and muscles, and even improving cognitive function.
Ideally, you want to drink about half your body weight in ounces per day, i.e. if you weight 150 pounds, you should drink 75 ounces of water a day.
-Stretching
The benefits are vast and the repercussions of failing to stretch can be dramatic.
Do yourself a favor and always stretch before and after a workout. This will promote a healthy cool down, improve flexibility, and reduce next day aches. Failure to stretch can lead to injures and muscle damage.
-Body Fat
This may seem like an obvious one, but it is one of the most important steps to a healthier you. Reducing your body fat has a lot of benefits such as:
Improved joints and tendons
Lowered risk of diabetes
Reduced risk of heart disease
Reduced inflammation
Better performance and endurance
Improved appearance and confidence
Better hormonal profiles in your body
Remember, it is not a race to see how quickly you can decrease your body fat. Healthy weight loss is around 1-2 pounds a week for your fitness goals.[2]
Crash dieting or pushing yourself too much in the gym can lead to you achieving an unrealistic target, and you may find yourself gaining all the weight you have lost.
Think of it as a lifestyle, and take it slow and steady.
