Medicine

san4es73 [151]3 years ago
5 0

Answer:

The given statement is TRUE

Explanation:

Friction is a force experienced by a body that resists its motion.

In other words, Friction is the force experienced by the two bodies (with uneven or rough surfaces) when moving against each other.

When an object slides on a surface, the surface area of the object in contact with the surface is more as compared to an object which is rolled on the surface. Therefore, the friction force experienced by the sliding body is greater than the rolling body.

Therefore, we can say that the rolling friction is less than the sliding friction.

What is the weight percent of vitamin c in a solution made by dissolving 6.50 g of vitamin c
kirza4 [7]

Answer:

10.6 % .

Explanation:

From the question above we can get the following parameters which we are going to use to solve the problem; mass of the solvent, which in this case is water= 55.0 grams and the mass of the SOLUTE which is the vitamin C, C6H8O6 in this problem = 6.50 grams.

Calculating the percent weight we are to divide the mass of the solute by the mass of the solution and multiply it by 100. This can be represented mathematically by using the equation below.

Percent weight= (mass of solute/ mass of solution) × 100.

Note that the mass of the solution is equal to the (mass of solute + mass of solvent) = 6.5 grams + 55.0 grams = 61.5 grams.

Hence, percent weight =( 6.5 grams/ 61.5 grams) × 100.

Percent weight = 0.10569105691 × 100 = 10.5691056911.

Percent weight = 10.6 %.

Describe how the tibial collateral ligament could be damaged if the knee is impacted on the lateral surface.
zhannawk [14.2K]

Answer:

the tibial collateral ligament can be damaged when the knee is impacted on lateral surface -

Sprain is mild stretch or tear , Sprain is partial tear and Sprain is full tear of the ligament .

Explanation:

Tibial Collateral ligament

Tibial Collateral ligament is one of the four important ligaments in knee. It joins femur with tibia or shinbone. The kneecap sits in the middle of this joint. Ligaments are very sensitive to strains. Tibial collateral ligament is most common ligament to get damage, specially for athletes. There could be three form of injury to this ligament.

Grade 1

Sprain is mild stretch or tear,

Grade 2

Sprain is partial tear and

Grade 3

Sprain is full tear of the ligament.

The damage occurs due to sudden force which is extensive for the ligament and it overstretches. Sudden impact on lateral surface will push the knee sideways, giving stress on the ligament, making it overstretch; and if the force is too great ligament will tear.
