Answer:
1/3
Explanation:
Gay Lusaac's law states that "the pressure of a given mass of gas is directly proportional with the absolute temperature of the gas, provided that the volume is kept constant."
In formula, we say that
P/T = k
Where
P = pressure at different points
T = temperature at different points
k = constant of proportionality
From the stated formula, if we multiply the temperature by 3, we have
P/3T = k
P * 1/3T = k
And from this, we see the pressure will change by a value of 1/3
Explanation:
It is given that,
Delfino is pushing the box with a force of 10 N to the left. Aleida is pushing the box with a force of 15 N to the right.
Aleida is exerting more force. He is the more stronger individual.
Net force is given by :
F = -10+15
F = 5 N
So, the net force is 5 N and it is in right direction.
Answer:
Yes, the velocity of the object can reverse direction when its acceleration is constant. For example consider that the velocity of any object at any time t is given as: ... At At t = 0 sec, the magnitude of velocity is 2m/s and is moving in the forward direction i.e.v (t) = -2.

Answer:
F = 150.6 N
Rx = 63.65 N
Ry = - 115.5 N
orientation is - 61.14 degree with horizontal
Explanation:
given data
moment arm m = 2 cm
angel = 115 degree
distance = 13 cm
force = 21 N
to find out
muscle force, vertical component force , horizontal component force , orientation
solution
we consider here Ra and Rb is reaction upside and
we know moment formula that is
moment at joint = F × sin(θ) × m - force × distance
0 = F × sin(115) × 2 - 21 × 13
F = 150.6 N
so
for horizontal component
sum of horizontal force = Rx + Fcosθ
0 = Rx + (150.6) cos115
Rx = 63.65 N
and
for vertical component
sum of vertical force = Ry + Fsinθ
0 = Ry + (150.6) sin(115)
Ry = - 115.5 N
and
reaction direction are
tan∅ = Ry / Rx
tan∅ = -115.5 / 63.65
∅ = - 61.14 degree
so orientation is - 61.14 degree with horizontal
