What is the distance from a point on the ground at an angle of elevation of 9 degrees to a hot air balloon that is 150m above the ground?
Using trigonometry and the sine ratio the distance is 959 meters to the nearest meter.
If you have a 2kg pendulum bob that is 6 meters above the ground at its high point and 1 meter at its low point how can you figure the kinetic energy?
To calculate the kinetic energy of the pendulum bob at its lowest point, you need to know its speed at that point. This can be calculated using the law of conservation of energy, where the gravitational potential energy at the highest point is converted into kinetic energy at the lowest point. Once you have the speed of the bob at the lowest point, you can calculate its kinetic energy using the formula: KE = 0.5 * m * v^2, where m is the mass of the pendulum bob and v is its velocity at the lowest point.
How many centimeters in point 018 meters?

In word form 0.008 meters?
eight thousandths meters or eight thousandths of a meter.
What is five point four five meters as centimeters?
1.00 meter = 100 centimeters5.00 meters = 500 centimeters5.45 meters = 545 centimeters
How long must a wire be to reach the top of a 13 meter telephone pole to a point on the ground 9 meters from the foot of the pole?
Use Pythagorean formula to solve: a2 + b2 = c2 , where a & b are the legs of the right triangle & c is the hypotenuse.so, a = 13m (height of the telephone pole) & b=9 m distance from the bottom of the pole.(13)2 + (9)2 = c2169 + 81 = c2c2 = 250c = SQRT(250)c = 15.81 m
How do astronauts communicate with their family in space?
Radio signals to a ground station, then usually telephone connection from the ground station to their family. The telephone connection may involve wire landlines, fiber optic lines, point to point microwave links, cell towers, etc.
How much is 42millimeter to meter?
1 mm = .001 meter Therefore, by moving the decimal point 3 places to the left, 42 millimeters equals .042 meters
What is the relief in an area where the highest point is 1200 meters above sea level and the lowest point is 200 meter above sea level?
the area where the highest and lowest point is 100.
How do you convert 1.2 meters into kilometers?
Converting Meters to KilometersSince 1 meter equals .001 kilometer, to convert 1.2 meters to kilometers, move the decimal point to the left three places. The answer is .0012 kilometers.
How many joules is 2.04 meters?
Joule is a unit for measuring energy. Meter is a unit for measuring length or distance. There is no conversion. If you wanted to find the potential energy of an object, 2.04 meters off the ground, then you would need to know the mass of the object and the value of g (gravitational acceleration) at the point where you are, then you could calculate energy in Joules.
How do you convert 2.05 meters into centimeters?
To convert 2.05 meters to centimeters, you multiply by 100 because there are 100 centimeters in one meter. So, 2.05 meters is equal to 205 centimeters.
