Answer: Direction
Explanation: A vector is a geometrical representation of physical quantity. It has a particular direction with a specific magnitude. In the geometry of space whether it is two dimensional or three dimensional the vector quantity has a specific direction. Such as a stone is thrown with a velocity in a particular direction.
The path of the stone in three-dimension shows its direction and speed is its magnitude.
Hence, the velocity of stone has two property magnitude mentioned as speed and particular direction. On writing the mathematical expressions for vectors, it is denoted by arrow mark on its top as shown below.
Answer:
at load 13114.85 N beam fail
Explanation:
given data
radius r = 6.7 mm
load = 2710 N
distance = 41 mm
length = 19 mm
to find out
At what load we expect this specimen to fracture
solution
we will first flexural strength that is
flexural strength = load × distance / πr³
flexural strength = 2710 × 41 ×
/ π(6.7 ×)³
flexural strength = 117.592 MPa
we know that for cross section specimen
flexural strength = 3load × distance / 2bd²
put here these value
117.592 × 
N/m² = 3 load × 41 × / ( 2 × (19×)³)
load = 117.592 × × ( 2 × (19×)³) / ( 3 × 41 × )
load = 13114.85 N
so at load 13114.85 N beam fail
Answer:
You should be physically active because you need to exercise or you might become overweight/obese. Exercise helps burn off calories which cause obesity. It is also good for your heart and lungs it keeps them active and healthy.
Answer: W = 294 J
Explanation: Solution:
Work is expressed as the product of force and the distance of the object.
W = Fd where F = mg
W= Fd
= mg d
= 15 kg ( 9.8 m/s²) ( 2m )
= 294 J
