Barker is unloading 20kg bottles of water from this delivery truck when one of the bottles tips over and slides down the truck r

<span>The primary force acting on the bottle is gravity. Since the incline is at 30 degrees, the full force of gravity does not apply as the ramp prevents the bottle from descending straight down. By calculating the sine of 30 degrees, it can be determined that the gravitational force acting on the bottle is 4.9 meters per second, and with the 20 kg weight of the bottle, the force acting on it is 98 Newtons.</span>

An airplane pilot wishes to fly directly westward. According to the weather bureau, a wind of 75.0 km/hour is blowing southward.
Softa [3030]

Answer:

The plane's speed in relation to the ground is 300.79 km/h.

Explanation:

Provided details include:

Wind speed = 75.0 km/hr

Plane's airspeed = 310 km/hr

Next, we must find the ground speed of the plane

Calculating the angle

Using the angle formula

\sin\theta=\dfrac{v'}{v}

Where v' represents the wind speed

v represents the plane's speed

We will substitute the values into the formula

\sin\theta=\dfrac{75}{310}

\theta=\sin^{-1}(\dfrac{75}{310})

\theta=14.0^{\circ}

Now, we must find the resultant speed

Using the resultant speed formula

\cos\theta=\dfrac{v''}{v}

Insert the values into the formula

\cos14=\dfrac{v''}{310}

v''=\cos14\times310

v''=300.79\ km/h

Consequently, the plane's speed in relation to the ground equals 300.79 km/h.

If white wool (W) is dominant over black wool (w), can two sheep with white wool produce an offspring with black wool? Explain y
inna [3103]
The response is affirmative .
An organism exhibiting the dominant phenotype can have two potential genetic combinations (for a gene with two alleles):
It might be homozygous dominant (WW) or
it can be heterozygous dominant (Ww), which is also known as a carrier

For instance, two black sheep can produce offspring with white wool if both are heterozygous dominant. In this scenario, both parents could pass on the recessive allele, resulting in their offspring inheriting the phenotype of white wool characterized by the genotype ww.
