Answer:
Explanation:
In the first attached image, we can see, the nomenclature used for Angle orientations.
To sum the vectors we must join the head of one of them with the tail of the next, at the end joins the tail of the first vector with the head of the last vector.
In the second attached image, we can find graphically the sum of each of the vectors.
The resultant vector has a length of 57.36[m], and goes 48° north of east.
 
        
             
        
        
        
Answer:
 W
 W
Explanation:
 = Temperature of the room = 22.0 °C = 22 + 273 = 295 K
 = Temperature of the room = 22.0 °C = 22 + 273 = 295 K 
 = Temperature of the skin = 33.0 °C = 33 + 273 = 306 K
 = Temperature of the skin = 33.0 °C = 33 + 273 = 306 K
 = Surface area = 1.50 m²
 = Surface area = 1.50 m²
  = emissivity = 0.97
 = emissivity = 0.97 
 = Stefan's constant = 5.67 x 10⁻⁸ Wm⁻² K⁻⁴
 = Stefan's constant = 5.67 x 10⁻⁸ Wm⁻² K⁻⁴
Rate of heat transfer is given as

If a body is traveling with constant speed , it means that it's distance is constantly increasing with time.
If it goes 5m in 3min , it will go 5m in next 3 min.
Average velocity is the total displacement divided by total time.
When the body travels 5m in 3 min and 25 m in next 3min , average velocity
=(25+5)/(3+3)
=30/6
=5m/min
        
             
        
        
        
Answer:
the one with a higher mass
Explanation:
The body with more mass will have the greater kinetic energy of the two. 
Kinetic energy is the energy due to the motion of body. It is mathematically expressed as: 
            K.E  =  m v²
  m v²
 m is the mass 
 v is the velocity 
  Since the velocity of the two bodies are the same, and mass is directly proportional to kinetic energy, the body with more mass will have a higher kinetic energy. 
  So between mass m1 and mass m2, the one with a greater mass will have a higher kinetic energy
