Answer:
17.56 N
Explanation:
Given that,
Mass of a crate, m = 5 kg
It is on a 21.0° hill
We need to find the y component of the weight.
y component = mgsinθ
Put all the values,
y-component = 5×9.8×sin(21)
= 49×sin(21)
= 17.56 N
So, the y-component of the weight is 17.56 N.
Yes. Here is my explaination: Peer pressure is a complicated area. On one hand, it can help your child develop the coping skills necessary for adulthood. It can also, however, lead them in bad directions. While teens may feel they have “grown up,” their brains are not finished developing and one of the immature functions is judgment. Peer pressure might encourage teens to become more active in athletics or to avoid risky behaviors. Or it could lead them to try alcohol or drugs, skip school or engage in other negative behaviors.

Answer:
Yes, it is possible.
It is called humidity. The quantity is reduced as the temperature go down. That’s why it condenses in a fridge or in a air conditioner unit. To create vapor there is various ways such as heating (evaporation) or fogging of liquid water. It will stop when the vapor pressure is reached and it depends of the temperature. The vapor pressure of water is 101.32 kPa at 100°C, which is the atmospheric pressure at sea level. It means that at that pressure and that temperature and above the water is totally converted in gas in the boiling process.
The object is moving with constant speed means there is no change in speed Hence the acceleration is 0
Where, u is initial speed,
v is final speed
t is time taken and
a is acceleration
a = ( v-u) /t
a =(0)/t because u=v
a=0
Therefore, Acceleration is 0
Wind Energy is the kind of energy will Cassie uses to power the boat.
What is wind energy?
The method of producing electricity using air or wind currents that naturally occur in the earth's atmosphere is known as wind energy (or wind power). Electricity is produced by modern wind turbines that harness the kinetic energy of the wind. Wind passing across the turbine's blades is the initial step.
What is the major problem with wind energy?
Wind energy has the potential to have negative environmental effects, including the possibility of reducing, fragmenting, or deteriorating habitat for wildlife, fish, and plants, as with all energy supply choices. Furthermore, flying animals like birds and bats may be harmed by turbine blades in operation.
