The relationship between the pressure applied to a gas and the volume of the gas is inverse. An increase in pressure reduces the volume of the gas. <span />
Answer:
s = 92.36 m
Explanation:
The distance covered by an object moving with uniform speed is given by the following formula:
s = vt
where,
s = distance covered by car during the time when driver was distracted in texting = ?
v = uniform speed of car = (95 km/h)(1 h/3600 s)(1000 m/1 km) = 26.39 m/s
t = time taken by the driver for texting = 3.5 s
Therefore, using these values in equation, we get:
s = (26.39 m/s)(3.5 s)
<u>s = 92.36 m</u>
This is a projectile motion problem, so, we use the formula for trajectory:
y =xtanα + gx^2/2v^2(cosα)^2
where
y is the vertical distance (y = 50 m)
x is the horizontal distance (x=90 m)
α is the angle of trajectory; since it levels of HORIZONTALLY, α = 0°
v is the initial velocity
g is the acceleration due to gravity which is 9.81 m/s^2
Substituting to the formula,
50 =90tan(0°) + (9.81)(90)^2/2v^2(cos0°)^2
v = 28.2 m/s
Answer:
The rotation of Earth on its axis causes electric currents to form a magnetic field which extends around the plane
Explanation:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents.
The total mass of the things on the road is 60 + 13, which is 73kg.
mass • acceleration = F
73 x 0.9m/s^2 = 65.7N
F = 65.7 N
