A constant net force of 20 n is applied to a 32 kg car, causing it to speed up from 4. 0 to 9. 0 m/s. how long is the force applied?
[tex]\green{ \underline { \boxed{ \sf{Force,F= Mass \times Acceleration }}}}[/tex]
So,
[tex] \sf Acceleration,a = \frac{Force}{Mass}[/tex]
[tex] \sf \implies \frac{20}{32} [/tex]
[tex]\implies \frac{5}{8} m/s^2[/tex]
Now,
By first equation of motion -
[tex]\green{ \underline { \boxed{ \sf{v-u=at}}}}[/tex]
So,
[tex]\sf t = \dfrac{v-u}{a} [/tex]
where
v = final velocityu = initial velocitya = accelerationt = time durationPutting Values -

scalable flexible and adaptable operational capabilities are included in
Ans The NRF guiding principles
Explanation:
The NRF is built on scalable, flexible, and adaptable concepts.
Scalable, flexible, and adaptable operational capabilities are indeed included in the (NRF)National Response Framework's five key principles.
The National Response Framework (NRF) is a comprehensive guide developed by the United States Department of Homeland Security to facilitate effective response and recovery efforts during emergencies, disasters, and incidents. The NRF's five key principles, known as the "Five Mission Areas," outline the fundamental aspects of emergency management. These mission areas include:
1. Prevention: Activities aimed at preventing emergencies or disasters from occurring. This involves measures such as risk assessment, hazard mitigation, and public education to minimize the likelihood of incidents.
2. Protection: Actions focused on safeguarding individuals, critical infrastructure, and key assets from potential threats and hazards.
3. Mitigation: Efforts to reduce the impact and severity of disasters by implementing measures to minimize the potential damage and disruption caused by hazards.
4. Response: Immediate actions are taken to address and manage the consequences of an incident. This includes coordinating emergency response activities, mobilizing resources, conducting search and rescue operations, providing medical assistance, and ensuring public safety.
5. Recovery: Activities aimed at restoring affected communities and rebuilding the impacted areas after an incident. This includes facilitating the recovery process, providing assistance to individuals and businesses, restoring critical services, and rebuilding infrastructure.
In summary, scalable, flexible, and adaptable operational capabilities are integral to the National Response Framework's five key principles, as they enable effective emergency management and response during various incidents and disasters.

The volume of the figure is the amount of space in it.
Using the assumed values, the volume of the cone is 37.68
How to calculate volumes?The question is incomplete; so I will give a general explanation on how volumes can be calculated..
Assume the figure is a cone of the following dimension:
Radius (r) = 3 meters
Height (h) = 4 meters
The volume of a cone is calculated as:

block x of mass m slides across a horizontal surface where friction is negligible. block x collides with block y of mass 2m that is initially at rest, as shown in figure 1. after the collision, both blocks slide together with a speed vs , as shown in figure 2.
The kinetic energy of the two-block system with the given masses before the collision is determined as ³/₂Mvs².
Kinetic energy of the blocks before collisionThe kinetic energy of the blocks before the collision is calculated as follows;
For a negligible friction effect, the kinetic energy of the two - block system after the collision is equal to the kinetic energy before the collision.
K.E(initial) = K.E(after)
K(after) = ¹/₂(m₁ + m₂)vs²
K(after) = ¹/₂(m + 2m)vs²
K(after) = ¹/₂(3m)vs²
[tex]K.E(after) = \frac{3}{2} Mv_s^2[/tex]
Thus, the kinetic energy of the two-block system with the given masses before the collision is determined as ³/₂Mvs².

Christopher runs a farm stand that sells apples and bananas. Yesterday christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163. 50. Today he sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76. 75. Determine the price of each pound of apples and the price of each pound of bananas
The equation computed shows that the price of apple is $2 and the price of banana will be $2.75.
How to compute the equation?Christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. This will be:.
35a + 34b = 163.50
He also sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76.75. This will be:
15a + 17b = 76.75
Equate both equations
35a + 34b = 163.50 ..... i
15a + 17b = 76.75 ...... ii
Multiply equation i by 15.
Multiply equation ii by 35
525a + 510b = 2452.50 .... iii
525a + 595b = 2686.25 .... iv
Subtract equation iii from iv
85b = 233.75
b = 233.75/85
b = 2.75.
The price of banana is $2.75.
The price of apple will be:
35a + 34b = 163.50
35a + 34(2.75) = 163.50
35a + 93.50 = 163.60
35a = 163.50 - 93.50
