How do you convert 1atmosphere into SI unit?
One atmosphere is equal to 101325 Pascals. One pascal in SI units is 1 kg m-1 s-2. Hence, 1 atmosphere in SI units is 101325 kg m-1 s-2.
What is the gravitational potential of a car with a mass of 1200 kg at the top of a 42 m high hill?
42 inches = 1.0668 meterPE = M g H = (1,200) (9.8) (1.0668) = 12,545.568 joules(rounded) relative to the bottom of the hill
What do get if you multiply newtons and meters?
This question cannot be answered in a sensible way. A Newton metre (or Joule) is a measure of energy or work, with dimensions [L2MT-2]. An inch is a measure of length, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information.
How many joules of work are done when a 20 kg box is lifted 5 meters above the floor?
980 w=m x g x d
What is the measure of kinetic energy of particles?
The SI unit of energy is the Joule. For example a 1 kg mass moving at 1 m/s would have half a joule of kinetic energy.
What is the kinetic energy in joules of a 850 lb motorcycle moving at 66mph?
Answer= 5703.55 Joules (see below for explanation)So Kinetic energy= 0.5 mv2Unit-wise 1 Joules = 1 kg m2s-2Therefore we need to convert 66mph -1 mph= 1.61 km/h66mph=106.22 km/h= 29.51 m/s =v OR (106.22 x 1000)/(60x60)Also need convert 850lbs to kg-1kg= 2.2 lbs1/2.2 kg = 1 lbTherefore 850 lbs= 1/2.2 x 850= 386.55 kg= mBack to the original equation KE= 1/2 mv2= 0.5 x 386.55 x 29.51= 5703.55 Joules = 5.7 KiloJoules
How many joules are equivalent to a momentum of 5 kg m/s?
The momentum of 5 kg m/s is equivalent to 25 joules.
How do you convert 1m3 iron to kg?
To convert 1 cubic meter (m³) of iron to kilograms (kg), you need to know the density of iron, which is approximately 7,870 kg/m³. Multiply the volume (1 m³) by the density: 1 m³ × 7,870 kg/m³ = 7,870 kg. Therefore, 1 m³ of iron is equivalent to approximately 7,870 kilograms.
What is 0.007 kg in joules?
To convert mass in kilograms to joules, you need to use the equation for gravitational potential energy (assuming a height). The formula is ( E = mgh ), where ( m ) is mass (0.007 kg), ( g ) is the acceleration due to gravity (approximately 9.81 m/s²), and ( h ) is the height in meters. Without a specified height, you cannot directly convert mass to energy in joules. If you provide a height, I can calculate the energy for you.
How do you convert megapascals to Kg-m?
To convert megapascals (MPa) to kilograms-force meters (kg-m), you can use the formula: 1 MPa = 10197.1621 kg-m. So, you would multiply the megapascal value by 10197.1621 to get the equivalent value in kg-m.
How many joules of potential energy does 10 kg box have that is 1 m from the floor?
The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object. Plugging in the values, we get PE = 10 kg * 9.8 m/s^2 * 1 m = 98 Joules.
How many joules energy does it take to raise 14 kg 1 meter?
To calculate the energy needed to raise an object, you can use the formula: energy = mass x gravity x height. Plugging in the values, we get: energy = 14 kg x 9.81 m/s^2 x 1 m = 137.34 Joules. So, it takes 137.34 Joules of energy to raise a 14 kg object by 1 meter.
What is the kinetic energy of a bicycle with a mass of 14kg traveling at a velocity of 3 ms?
KE = 1/2*mass * velocity^2 KE = 1/2(14 kg)(3 m/s)^2 = 63 Joules
What is the potential energy of a 1 kg mass 1 m above the ground?
The potential energy of a 1 kg mass 1 m above the ground can be calculated using the formula: Potential Energy = mass * gravitational acceleration * height. Given this scenario, the potential energy would be 1 kg * 9.81 m/s^2 * 1 m = 9.81 Joules.
What is the kinetic energy of a 855 kg car with a velocity of 15.5 ms?
Classical kinetic energy in joules (assuming the speed of the object is much less than the speed of light) is given by: E = 1/2 m v2 where m is the mass in kilograms (kg), and v is the speed in metres per second (m s-1) So in this case, m = 15 kg, and v = 2 m s-1 E = 1/2 x 15 x 22 = 30 joules
How do you convert 1 cu ft of sand to kg?
To convert 1 cubic foot (cu ft) of sand to kilograms (kg), you need to know the density of the sand, which typically ranges from about 1,440 to 1,600 kg/m³. First, convert cubic feet to cubic meters (1 cu ft ≈ 0.0283168 m³). Then, multiply the volume in cubic meters by the density of the sand. For example, if using a density of 1,600 kg/m³, the calculation would be: 1 cu ft × 0.0283168 m³/cu ft × 1,600 kg/m³ ≈ 45.36 kg.
What is the kinetic energy of 2 kg mass moving at a velocity of 20meter per seconds?
KE = 1/2 M V2 = 1/2 (2) (20)2 = 400 kg-m2/sec2 = 400 joules
