Answer:

v = dr/dt = 7t x + 0 y + (- 4) z

a = dv/dt = 7 x + 0 y + 0 z

t = 0:

v = (-4) z

a = 7 x

Explanation:

v = dr/dt = 7t x + 0 y + (- 4) z

a = dv/dt = 7 x + 0 y + 0 z

t = 0:

Help please physics !!
malfutka [58]

Answer:

Option A. 1 bar = 1 atm

Explanation:

Pressure has various units of measurement. Each unit of measurement can be converted to other units of measurement. For example:

1 atm = 1 bar

1 atm = 760 mmHg

1 atm = 760 torr

1 atm = 1×10⁵ N/m²

1 atm = 1×10⁵ Pa

With the above conversion scale we can convert from one unit to the other.

Considering the question given above, it is evident from the coversion scale illustrated above that only option A is correct.

Thus,

1 bar = 1 atm
