(b) different
(b) 10.8 x 103 N/m3
(c) density of cork is less than the density of water.
(b) lactometer
The force exerted by a thin and strong string is distributed to very less area and hence the force applied due to the bag is more, the pressure exerte...
Here, mass of packet, M – 500 g volume of the packet, V = 350 cm3 Clearly, density of packet, d = = = Since the density of packet is more than ...
Density of water, dw = 1 g cm-3 Mass of substance, m = 50 g Volume of substance, V = 20 cm3 ∴ Density of substance = = 2.5 g cm-3 As th...
The buoyant force acting on the block of plastic is more than its weight. As a result of this, it comes up when released under water. The cause of t...
If an object is immersed in a liquid then the buoyant force due to liquid acts on the object in vertically upward direction.
Here, time of ascent = time of descent, = 3s (a) v = 0, a = -g = -9.8 m/s2 From v = u + gt 0 = u - 9.8 x 3 u = 29.4 m/s (b) From v2 - u2 ...
Here, h = 100 m. Let the two stones meet after t seconds at a point P which is at a height x above the ground as shown in figure. 2s.png For ...
Mass of the earth, Mass of the sum, Distance between the earth and the sun, R = Then, the gravitational force between the earth and the sun...
Here, u = 40 m/s, g = -10 m/s2 h = ? v = 0 From v2 - u2 = 2gh, 0 - (40)2 = 2 (-10)h or h = = 80 m As final position of the stone coincides...
Initial velocity, u = 0 ms-1 Final velocity, v = ? Height of the tower, h = 19.6 m Acceleration due to gravity, g = 9.8 ms-2 Using the equatio...
Initial velocity, u = 49 m/s Acceleration, a = g = -9.8 m/s2 Velocity at the highest point, v = 0 m/s (i) If h is the maximum height reached by ...
Here, m = 10 kg Mass is the same on earth and moon. Now, weight of the object on earth, We, = mge = 10 × 9.8 = 98 N Weight of the object on mo...
A sheet of paper will fall slower than the one that is crumpled into a ball. This is because the air offers resistance due to friction to the motion o...
We know that the value of g is greater at the poles than at the equator. So the weight of gold at the equator will be less than the weight of gold at ...
