If 90 percent of an object is floating below water what is its density?
Let's say the object has mass M and volume V. An object floats by displacing an amount of water equal to the object's mass. So water equal to 90% of the volume of the object has mass equal to the whole object, or M = 0.9V * 1g/ml or M = 0.9V Since density is mass divided by volume, or d = M/V, density of object = M/V = 0.9 g/ml.
How is mass of an object measured?
It is the force of gravity divided by the weight of the object, written as M=N/9.81, where M is the mass and w is the weight of the object in Newtons.
What is the potential energy of a 5 kg object sitting on a shelf 3 m high?
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
What does the m stand for in the formula for kinetic energy?
m stands for Mass of the object
What determines how hard it would be to stop an object in motion.?
The equation is F = M A, where F is the Force required to stop the object, M is the object's Mass, and A is its Acceleration. Note that its acceleration in this case is the rate at which you are DE-ACCELERATING the object to stop it.
what is something natural that is about 7 m high?
exchange gases through their moist body surface ?
What is a volume of a room that is 5 meters wide 7 meters long and 10 meters high?
volume = width x length x height (for a rectangular object) = 5 m x 7 m x 10 m = 350 m3
What is the density of natural gas?
About .7-.9 kg/m^3
What does m to the second power mean?
m to the second power means multiply m by itself, or m x m.
What is the diameter of a mango seed?
7-12 m high
How high up the wall will a 7-m ladder touch if the foot of the ladder is placed 2 m from the wall?
About 6.708 m using Pythagoras' theorem
What are the release dates for Marcus Welby M-D- - 1969 Friends in High Places 5-7?
Marcus Welby M-D- - 1969 Friends in High Places 5-7 was released on: USA: 23 October 1973
What is gravitatioal potential energy?
Ug= mgh where m is the mass of the object g is the gravitational constant (9.8 m/s/s on earth) and h is the high above the ground
What is the formula a equals F m?
a = F/m is Newton's 2nd Law. It means that an object's acceleration ' a ' is the samevalue as dividing the force applied to the object ... ' F ' ... by the object's mass ' m '.
What is the least common denominator of 3 over 7 and 4 over m?
The LCM of 3/7 and 4/m is 7*m if m is not a multiple of 7, and m if m is a multiple of 7.
How do you find the force of objects?
To find the force on an object, you multiple the mass of the object by its accelerationFor example, let's say a ball is moving at 7 m/s squared and has a mass of12 kg.The formula for force is: F = maF = 12 kg x 7 m/s squaredF = 84 N ( the unit for force is N, which is Newtons)*Be careful, an object does not "have a force". A force is an action that can modify the shape of an object and/or modify its velocity. Therefore, you do not calculate the force of an object, but the force required to give it a certain acceleration.
What is the volume of an object that is 5.20m high 9.5m long and 8.75m wide what is the volume?
432.25 m^3 However, if we're holding true to the margin of error, it is actually 432.2 m^3
