What is the speed of an object weighing 80 pounds dropped from 7 feet?
it strikes the ground at a velocity of 17.9 ft/s
What does hydrostatic weighing mean?
Hydrostatic weighing, also called underwater weighing, involves being weighed underwater.requires one to be completely submerged in water for a few seconds. ref. http://www.wisegeek.com/what-is-hydrostatic-weighing.htm
A student is using weighing paper and a triple-beam balance to measure the mass of a power. which of the following steps should a student carry out first?
pour the sample on the weighing paper
Which is one of the way that Dishonest shopkeepers fool customers while weighing things with a weighing balance do?
shopkeepers do this by writing 1 kg on a weigh which is actually of half kg and when they balance it they take the money of 1 kg, but in real they have given only half kg
Calculate the kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph?
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
How much kinetic energy in a fast moving cricket ball?
The kinetic energy of a cricket ball depends on its mass and velocity. For example, a cricket ball weighing 160 grams and traveling at a speed of 140 km/h (38.89 m/s) would have a kinetic energy of about 110 joules.
What is the pressure at impact of a 5000 lb vehicle traveling 15 mph hitting an object?
if a truck weighing 5000 lbs traveling 15 mph hits an object , what is the pressure at impact?
What is the speed of an object weighing 80 pounds dropped from 7 feet?
it strikes the ground at a velocity of 17.9 ft/s
What is the legal velocity of a 177 pellet in the UK?
A pellet weighing 7.9 grams can not exceed 826/FPS See the link below
A sled weighing 100 N is held in place on a frictionless 20 degree slope by a rope attached to a stake at the top. The rope is parallel to the slope What is the normal force of the slope acting on?
the normal force is acting on the sled-- it's what keeps the sled from falling through the slope
What speed will a women weighing 50 kg need to run in order to match the momentum of a women weighing 60 kg who is running 5 meters per second?
The momentum of an object is given by its mass multiplied by its velocity. To match the momentum of the woman weighing 60 kg running at 5 m/s, the woman weighing 50 kg would need to run at a speed of 6 m/s ( 60 kg * 5 m/s / 50 kg = 6 m/s).
What is the de Broglie wavelength in meters of a baseball weighing 145 and traveling at 152?
You can use De' Broglie's equation. I think it is wavelength = plank's constant/mass of the object *velocity.velocity is unknown in this case, m= 154g and wavelength is 0.450*10-90.450*10-9 = look up the value of plank's constant/ 0.145 kg* Velocity.Rearrange the equation to get velocity of an object.
Why is it necessary toallow most products to dry before weighing them?
Allowing products to dry before weighing helps ensure accuracy in measurements. Moisture can add weight to the product and affect the calculation, leading to an incorrect measurement. Drying the product first removes this variable, resulting in more precise and reliable weight measurements.
A disc weighing 2 kg rolls without slipping over a horizontal plane with a velocity 4 ms1 Find the kinetic energy of the disc?
The kinetic energy of the disc can be calculated using the formula: KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the disc, and v is the velocity. Plugging in the values: KE = 0.5 * 2 kg * (4 m/s)^2 = 16 J. So, the kinetic energy of the disc is 16 Joules.
Steps for weighing an object?
Obtain an appropriate weighing device. Make sure the device is calibrated properly. Perform the weighing by placing the object on top of the weighing device.
Is it said weighing a cake or scaling a cake?
