Answer:
[tex]\boxed {\boxed {\sf 252.5 \ Newtons }}[/tex]
Explanation:
Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.
[tex]F=m*a[/tex]
The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:
[tex]m= 50.5 \ kg[/tex][tex]a= 5.0 \ m/s^2[/tex]Substitute the values into the formula.
[tex]F= 50.5 \ kg * 5.0 \ m/s^2[/tex]
Multiply.
[tex]F=252.5 \ kg*m/s^2[/tex]
1 kilogram meter per square second is equal to 1 Newton. Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.[tex]F= 252.5 \ N[/tex]
The force required is 252.5 Newtons.

Koby placed ½ teaspoon of baking soda into each of two identical glasses. He noticed the baking soda was lumpy, so he used a fork to break up the lumps. Why is it important to break up the lumps?
Answer:
because the lumps are just baking soda covered with whatever watery substance you used.
Explanation:
so pretty much inside the lumps is just a bunch of baking soda

Kamal, Kamala, Krishna invert a sum of RS= 30,000 on a business in the ratio 2 : 3 : 5. Find the each of their investment.
Answer:
Explanation:
Kamal, Kamala, Krishna invert in the ratio 2 : 3 : 5.
As 2+3+5 =10, their respective share is 2/10, 3/10 and 5/10.
Sum of investment = 30000Rs
Kamal's investment = 30000 * 2/10 = 6,000 Rs
Kamala's investment = 30000 * 3/10 = 9,000 Rs
Krishna's investment = 30000 * 5/10 = 15,000 Rs

a car is traveling along the highway at a constant velocity, what must be true about all the forces acting on the car?
A golfer wants his shot to land
122 m away on flat ground.
His club launches balls at a 55.0°
angle. How fast should
the ball leave the club?
(Unit = m/s)
Answer:
35.67 m/s
Explanation:
Applying the formular for range,
R = u²sin2∅/g....................... Equation 1
Where R = Range, u = Initial Velocity, ∅ = angle of launch, g = acceleration due to gravity
make u the subject of the equation
u = √(Rg/sin2∅)............. Equation 2
Given: R = 122 m, g = 9.8 m/s², ∅ = 55°
Substitute these values into equation 2
u = √[(122×9.8)/(sin(2×55))]
u = √(1195.6/sin110)
u = √(1272.33)
u = 35.67 m/s
Answer:
35.67

Air from a metal can is removed so the pressure in the can decreases to 70000Pa, the can is then sealed. The pressure from outside the can is atmospheric pressure which is 100kPa. The area of one side of the can is 1.5m2, find the resultant force on this side of the can.
Answer:
F = 45 KN = 45000 N
Explanation:
Considering the downward direction as the positive direction:
[tex]P = P_1 - P_2[/tex]
where,
P = Resultant Pressure = ?
P₁ = Atmospheric Pressure = 100 KPa
P₂ = Pressure inside the can = 70000 Pa = 70 KPa
Therefore,
[tex]P = 100\ KPa - 70\ KPa\\P = 30\ KPa[/tex]
Now the resultant force will be given as:
[tex]F = PA[/tex]
where,
F = resultant force = ?
A = Area of side of can = 1.5 m²
Therefore,
[tex]F = (30\ KPa)(1.5\ m^2)\\[/tex]
F = 45 KN
How does friction affect the output of machines?
Answer:
In a machine, friction reduces the mechanical advantage, or the ratio of output to input: an automobile, for instance, uses one-quarter of its energy on reducing friction. Yet, it is also friction in the tires that allows the car to stay on the road, and friction in the clutch that makes it possible to drive at all

What is the origin behind the term " cell phone "
Answer:
Rae Young at Bell Labs. They diagrammed a network of wireless towers into what they called a cellular layout. Cellular was the chosen term because each tower and its coverage map looked like a biological cell. Eventually, phones that operated on this type of wireless network were called cellular phones.

why is fluorine more chemically reactive than
nitrogen?
Answer:
Nitrogen has Electronic configuration 1s2 2s2 2p3. Fluorine has Electronic configuration 1s2 2s2 2p5 i.e. nitrogen has half filled p subshell that makes it more stable than fluorine and fluorine requires only 1 electron to complete it's octet to get stable..Therefore Fluorine is more reactive than Nitrogen.

what is the velocity of a car that went a distance of 400ft in 25 seconds
Speed = (distance covered) / (time to cover the distance)
Speed = (400 ft) / (25 seconds)
Speed = 16 ft/sec
That's the car's speed.
We don't have enough information to state its velocity.
A student of mass 45kg, who is undergoing National Service training, takes 6s to climb a flight of stairs that had 36 steps. If each step is 16cm high, what is the power of the student?
Answer:
Approximately [tex]4.2 \times 10^{2}\; \rm W[/tex] on average in the vertical direction (assuming that [tex]g = 9.8\; \rm N \cdot kg^{-1}[/tex].)
Explanation:
Vertical displacement of this student in [tex]6\; \rm s[/tex]: [tex]36 \times 16\; \rm cm = 36 \times (0.16\; \rm m) = 5.76\; \rm m[/tex].
Average vertical velocity of this student: [tex]v = \displaystyle \frac{5.76\; \rm m}{6\; \rm s} = 0.96\; \rm m \cdot s^{-1}[/tex].
The average vertical force that this student exerts on the ground would be equal to the weight of this student:
[tex]F = W = m \cdot g = 45\; \rm kg \times 9.8\; \rm N \cdot kg^{-1} = 441\; \rm N[/tex].
The average power of this student in the vertical direction is equal to the product of the force and velocity of this student in that direction:
[tex]P = F \cdot v = 441\; \rm N \times 0.96\; \rm m \cdot s^{-1} \approx 4.2\times 10^{2}\; \rm W[/tex].
