Laccolith is a mushroom-shaped pluton that forms by injecting magma between sedimentary strata, forcing the upper layers to arch upward.
Answer:
39.4 kJ
Explanation:
Given mass = 25.0 g
Specific heat of ammonia (g) = 4.7 J/g.K
Specific heat of ammonia (l) = 2.2 J /g.K
ΔHvap = 23.5 x 10³ J /mol
Heating liquid ammonia from -65 °C to -33.4°C
Q₁ = m s ΔT = = 25.0 g * 4.7 J/g.K * [-33.4 - (-65)] °C = 3713 J
Evaporating 25 g of ammonia at -33.4°C
Molar mass of ammonia = 17 g/mol
Thus, moles = 25 / 17 moles
Q₂ = (25 / 17) mol * ΔHvap = 1.470 mol * 23.5 x 10³ J /mol = 34558.8 J
Heating NH₃(g) from -33.4°C to -12.0°C
Q₃ = m s ΔT = = 25.0 g * 2.2 J/g.K * [-12.0 - (-33.4)] °C = 1177 J
<u>Total heat energy = Q₁ + Q₂ +Q₃ = 39448.8 J = 39.4 kJ (As 1 J = 10⁻³ kJ)</u>
The inner planets are;- Mercury, Venus, Earth and Mars. Earth is the only planet which has atmosphere, water on the surface or know of to have water(Mars might have water underground), and life.
Mercury is pretty much a small planet on fire by day, but freezes at night.
Venus is a gas planet which is usually on fire in places too, but has mass ice craters on the surface.
Earth, well just look out your window.
Mars may have been an earth like planet at one stage, (still unknown) but is known as the red planet due to its volcanic activity. Mars also has the biggest mountain/volcano on any known planet called Mt Olympus. It's 3 times the size of Mt Everest.
Hope this helps!! :)
Answer:
<h2> v= 21.47m/s </h2>
Explanation:
For the car to turn at the about the centripetal force must not be greater than the static friction between the tires and the road
we will use the expression relating centripetal force and static friction below
let U represent the coefficient of static friction
Given that
U= 0.50
mass m= 1200-kg
radius r= 94.0 m
Assuming g= 9.81 m/s^2
substituting our given data in to expression we can solve for the speed V
making v the subject of formula we have
v= 21.47m/s
<em><u>hence the maximum velocity of the car is 21.47m/s</u></em>
I think it is a, b, and e. Hope it helps! :)
