I believe it is because of weight if Timmy is larger and bigger than Maria that would mean he would stop slower just because of his bodyweight pushing on the back of the skateboard while Maria is all those skinny and she doesn’t have as much weight as she can go farther
Answer:
1.05 J.
Explanation:
Kinetic Energy: This is the energy possessed by a body due to its motion. The S.I unit of kinetic energy is Joules (J). The formula of kinetic energy is given as
Ek = 1/2mv²................. Equation 1
Where Ek = kinetic energy, m = mass of the uniform rod, v = liner velocity of the rod.
But,
v = αr .......................... Equation 2
Where α = angular velocity of the rod, r = radius of the circle.
Given: α = 3.6 red/s, r = 120/2 = 60 cm = 0.6 m.
Substitute into equation 2
v = 3.6(0.6)
v = 2.16 m/s.
Also given: m = 450 g = 0.45 kg.
Substitute into equation 1
Ek = 1/2(0.45)(2.16²)
Ek = 1.05 J.
Answer:
required distance is 233.35 m
Explanation:
Given the data in the question;
Sound intensity 
= 1.62 × 10⁻⁶ W/m²
distance r = 165 m
at what distance from the explosion is the sound intensity half this value?
we know that;
Sound intensity is proportional to 1/(distance)²
i.e
∝ 1/r²
Now, let r² be the distance where sound intensity is half, i.e ₂ = ₁/2
Hence,
₂/₁ = r₁²/r₂²
1/2 = (165)²/ r₂²
r₂² = 2 × (165)²
r₂² = 2 × 27225
r₂² = 54450
r₂ = √54450
r₂ = 233.35 m
Therefore, required distance is 233.35 m

</span>Meiosis has 2 cell divisions but mitosis has only one cell
division. Meiosis I is same as mitosis because parent cell produces diploid
cells. But the difference between meiosis and mitosis is after the complete
process meiosis produces genetically different haploid daughter cells and
mitosis produces genetically same diploid daughter cells.
<span>2.
</span>The main advantage of the sexual reproduction is It helps to produce offspring which can be
well adapted to the environmental conditions due to the genetically
differentiations. Hence, there are various types of offspring in the population.
But the disadvantage is it requires two parents and it requires more time than
asexual reproduction.
<span>3.
</span>Advantages
of asexual reproduction are it requires only parent, time for the process is
relatively low, it produces genetically identical offspring. The main
disadvantage is due to the production of genetically identical offspring, the
survival rate is low when there is a disaster.
<span>4.
</span><span>The
organism can do either sexual reproduction or asexual reproduction to produce
offspring. If it is difficult to find a partner to mate, the living being can
do asexual reproduction to make offspring in a short period of time. When the
organism needs genetically different offspring for survival, they can do sexual
reproduction.</span>
Hi, thank you for posting your question here at Brainly.
For consistency you must convert gallons to cubic foot. The conversions are:
7.481 gal = 1 ft3
Then, $3.65 per gallon becomes $27.3 per ft3. If you buy $40 worth of gas, you get $40/$27.3 = 1.46 ft3 of gas.
If you can travel for 4 miles per ft3, then with the amount of gas you have, you can travel up to 5.85 miles.
(4 miles/ft3)*(1.46 ft3) = 5.85 miles
