Answer:
Force on each front wheel = 4711 N
Force on each back wheel = 2591 N
Explanation:
Weight of car = 1490 Kg
Distance of COG from front axle= 1.1 m
Distance of COG from back axle = 3.1 - 1.1 = 2 m
Vertical forces are balanced ,
So, R1 + R2 = mg
R1 + R2 = 1490× 9.8
Thus; R1 + R2 = 14602 - - - eq1
Where
R1 is force on front wheel
R2 is force on back wheel
Now, we know that;
Angular momentum about centre of gravity is zero.
Therefore,
R1 × 1.1 = R2 × 2
R1 = (2/1.1)R2
Put this into equation1, to get;
(2/1.1)R2 + R2 = 14602
R2(2.818) = 14602
R2 = 14602/2.818
R2 = 5182 N and R1 = (2/1.1)5182 = 9422 N
Hence, force on each back wheel = R2/2 = 5182/2 = 2591 N
Force on each front wheel = R1/2 = 9422/2 = 4711 N
Answer:
-20°C
Explanation:
The specific heat capacity of ice using the cgs system is 0.5cal/g°C
The enthalpy change is calculated as follows
ΔH=MC∅ where M represents mass C represents specific heat and ∅ represents the temperature change.
10cal = 2g×0.5cal/g°C×∅
∅=10cal/(2g×0.5cal/g°C)
∅=10°C
Final temperature= -30°C+ 10°C= -20°C
Answer:
Below:
Explanation:
Consider two rays originating from the bottom of the pond. As these rays get refracted into the air, they bend away from the normal. ... This point gives the apparent position of the bottom of the pond, therefore, the pond appears to be shallower.
Hope it helps....

Answer:
1609.1429 rad/sec
Explanation:
By using the relation Angular velocity and frequency as:
Angular velocity (ω) = 2×π×Frequency (ν)
Given the frequency = 256 vibrations per second.
So, Angular velocity can be calculated by using the above formula as:
Angular velocity (ω) = 2×π×Frequency (ν)
⇒Angular velocity (ω) = 2×π×256 rad/ sec
⇒Angular velocity (ω) = 2×(22/7)×256 rad/ sec
<u>⇒Angular velocity (ω) = 1609.1429 rad/ sec</u>
