find a if
s= 128
u= 7
t= 8
from the formula
s= ut+1\5 (at) square
Answers
Answer:
I think formula will be S=ut+1/2 (at) ^2
then,
128=7*8+1/2(a*8) ^2
128=56+1/2(64a^2)
128-56=32a^2
72/32=a^2
a^2=9/4
a=+-√9/4
a=+-3/4
hope it's clear to you mate☺
Environmental science is an interdisciplinary academic field that integrates physical, biological and information sciences (including ecology, biology, physics, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.

Environmental engineering focuses on design and technology for improving environmental quality in every aspect.
Environmental scientists study subjects like the understanding of earth processes, evaluating alternative energy systems, pollution control and mitigation, natural resource management, and the effects of global climate change. Environmental issues almost always include an interaction of physical, chemical, and biological processes. Environmental scientists bring a systems approach to the analysis of environmental problems. Key elements of an effective environmental scientist include the ability to relate space, and time relationships as well as quantitative analysis.
