A free-body diagram shows the vectors for all the force acting on the body the resultant vector found by summing all the individual vectors represents the net force.

Using Diagrams to Depict ForcesWhen learning about force diagrams, you saw that scientists draw a diagram using arrows to show the type and size of the force. The object is shown as a small box or dot from which the arrows originate. These diagrams are also called free-body diagrams . A "free body" is one object drawn all by itself, even though that object is likely to be in contact with other objects. This way you can focus all your attention on what is happening to that one object.

Sophie throws a tennis ball down from a height of 1.5 m at an angle of 450 with respect to vertical. She drops another tennis ba

Katena32 [7]

Given that,

Height =1.5 m

Angle = 45°

We need to find the greater speed of the ball

Using conservation of energy

$P.E_{i}+K.E_{f}=P.E_{f}+K.E_{f}$

$mgh+\dfrac{1}{2}mv_{i}^2=mgh+\dfrac{1}{2}mv_{f}^2$

Here, initial velocity and final potential energy is zero.

$mgh=\dfrac{1}{2}mv_{f}^2$

Put the value into the formula

$9.8\times1.5=\dfrac{1}{2}v_{f}^2$

$v_{f}^2=2\times9.8\times1.5$

$v_{f}=\sqrt{2\times9.8\times1.5}$

$v_{f}=5.42\ m/s$

Hence, the greater speed of the ball is 5.42 m/s.

Which physical property is used to test the purity of metal ?

dimulka [17.4K]

The physical and chemical properties of metal can differ between the elements but if we try and generalize.

Physical properties are that they are hard, dense, shiny, malleable (can be bent), ductile (can be pulled into wires), a good conductor of heat and have high melting points meaning that they are solid at room temperature

Their chemical properties include being good electrical conductors, they make metallic bonds (ionic bonds with non-metals) and their atoms are arranged in a lattice. They release hydrogen when reacted with acids and are usually cations (positive ions).
