Question 33 (01.04 LC) Forensic technicians receive OSHA data sheets regarding toxic chemicals they deal with in their labs.
True False
Question 34 (04.04 LC) Comprehensive studies have shown that forensic scientists should look for between 8 to 16 points to establish identification based on fingerprints. True False
Physics

Karolina [17]4 years ago
6 0

Answer:

A) true

33) Osha data : true

34 ) False

Explanation:

A) Karl Landsteiner was the first to classify blood on the basis of modern theory .

33) OSHA ( Occupational Safety and Health Administration ) data relates to the safety measures that are taken by a unit or firm to avoid hazardous situation for their workforce.

34 ) There are as many as 150 points in an average finger prints that can be compared. Some country  like England requires 16 point identification , some like France requires 17 points identification. So The statement is wrong.

State ohms law and derive the relation between current flowing through a circuit and potential difference across the ends of the
dem82 [27]

Answer:

Voltage = current * resistance

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

V = IR

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

An animal-rescue plane flying due east at 55 m/s drops a bale of hay from an altitude of 69 m . The acceleration due to gravity
Bogdan [553]

Answer:

The momentum of the bale the moment it strikes the ground is 1076.68 kg-m/s.

Explanation:

It is given that,

Velocity of an animal-rescue plane, v_x=55\ m/s

It drops a bale of hay from an altitude of 69 m, h = 69 m

The vertical velocity of plane is given by :

v_y=\sqrt{2gh}

v_y=\sqrt{2\times 9.81\times 69} =36.79\ m/s

Weight of the bale of hay, W = 192 N

If m is the mass, then weight is given by :

m=\dfrac{W}{g}

m=\dfrac{192}{9.81}=19.57\ kg

The resultant momentum of the bale the moment it strikes the ground is given by :

p=m(v_x-v_y)

p=19.57\times 55i-19.57\times 36.79j

p=(1076.35i-719.98j)\ kg-m/s

Magnitude of momentum,

p=\sqrt{1076.35^{2}+719.98}

p = 1076.68 kg-m/s

So, the momentum of the bale the moment it strikes the ground is 1076.68 kg-m/s. Hence, this is the required solution.
